Germany were fresh off a 3-1 win over the USA on Nagelsmann's debut, but rode their luck in a keenly contested first half, with Mexico's Hirving Lozano unable to take advantage of some early defensive lapses. Nagelsmann's side began to find joy up the left-hand side midway through the half, though, and were rewarded when Robin Gosens flicked on Leroy Sané's near-post corner for Antonio Rüdiger to sink the opener. After the offside flag denied Thomas Müller Germany's second goal, Mexico levelled straight after play resumed through Uriel Antuna.
Nagelsmann introduced Füllkrug and Leon Goretzka at the start of the second half, but his plans were thrown into momentary disarray when Erick Sanchez headed Mexico into a 47th-minute lead. Goretzka headed over as Germany sought an immediate response, and they got it with their next attack. Guillermo Ochoa denied Florian Wirtz's header, but not substitute Füllkrug's instinctive follow-up. Ochoa had to be on his toes to prevent substitute Jonas Hofmann getting on the end of a probing Jamal Musiala pass as Germany searched for a winner. At the other end, Füllkrug got in the way of a dangerous-looking free-kick. Nagelsmann handed Kevin Behrens his senior international debut in the closing stages, but Mexico kept the Union Berlin forward and his new teammates at bay.

Behrens debut
One of three new call-ups, Kevin Behrens makes his Germany debut at the age of 32. The Union striker has scored four times in the Bundesliga so far this season...
Germany are beginning to find gaps in the Mexico defence as Goretzka sends a ball into the area. Hofmann and Sané are lurking, but Ochoa is quickest to it.

Superb vision!
Musiala draws the attention of a clutch of green shirts, before releasing the ball for the run of Hofmann. Ochoa beats him to it, though.
66'
Double change
Leipzig's David Raum replaces left-back Gosens, who had been one of Germany's best outlets. Jonas Hofmann is also on, replacing Leverkusen teammate Wirtz. Talk about strength in depth!
Süle makes way for Schalke-reared Thiaw at the back. It was the other way round against the US at the weekend. Nice selection headache for Nagelsmann to have.
Mexico can't get to grips with Sané, who waltzes in off the right once more. He tries to play a give and go with Musiala, but the return ball is picked off.
55'
What a record!
That's now nine goals in 11 senior Germany appearances for Füllkrug. The 30-year-old only made his debut last November, remember.
51'
Füllkrug levels!
All square again in Philadelphia. Sané arrows in a cross for the head of Wirtz, who forces a flying save from Ochoa. Füllkrug then uses all his instinct to hammer in the rebound. That's exactly what he was brought on to do!
Another Sané corner almost produces the equaliser. Gosens flicks it on, as he did for Rüdiger's goal, but Goretzka can't keep his close-range header down. What a response that would have been!
47'
Mexico lead!
That wasn't in the script for Germany. Antuna has all the time in the world to pick his cross, and there's Sanchez, taking advantage of a Süle slip, to head Mexico ahead.
Müller was unlucky not to mark his 125th Germany cap with a goal. Füllkrug - a natural No.9 - is his replacement. Bayern's Goretzka is also on in central midfield for Groß.
Sané doesn't have the height to reach Musiala's attempted cross, and that's it for a keenly contested first half in Philly. Food for thought for Nagelsmann, who has Niclas Füllkrug on the bench.

Ter Stegen alert
Mexico break after Sané loses possession. Antuna races in on goal, but ter Stegen is quick to read the danger and races out of his area to hoof clear.

Two bites at the cherry!
Mexico are taking no chances as Rüdiger swings a cross towards Musiala. Gündogan meets the ensuing corner at the near post with an effort that's blocked. His second attempt then whistles past the far post.

Mexico equalise
Lozano picks off Rüdiger's attempted clearance and drives into the box, snaking round Süle before dropping it off for Antuna to score from close range.
Ochoa beats away an effort from Groß as Germany win a corner. Wirtz feeds Müller, who slams in a second goal - but it's ruled out for offside.
34'
Over!
Gimenez meets a Gallardo free-kick ahead of ter Stegen, but can't keep his header down. Big chance not taken!
Happy days!
That's Rüdiger's third senior international goal, on his 64th Germany appearance. Strange to think he didn't manage to break into the Dortmund first team in his younger days. Instead, he got his big break after leaving the BVB U19s for Stuttgart.
Sané swings in a corner that's cleared. He takes the second attempt, finding Gosens at the near post. The Union Berlin man flicks it over to the back stick, where Rüdiger rises highest to head home.
Germany work the left-hand side again with Gosens and Gündogan. Musiala helps it on in the box for Sané, whose back-heeled attempt is blocked by a defender.

No way through
Müller touches Rüdiger's long ball out to the left for Gosens, whose cross is hooked away.

Speculative cross
Süle advances with the ball, but his cross is fended clear by Ochoa. Germany are still to find their groove...

Musiala probing
Musiala has the ball at his feet on the right-hand side of the Mexico area. The shot is on as he jinks into space, but the Bayern talent instead tries to play in a teammate and Mexico can clear.

Knocking at the door
Gosens blocks a cross at the expense of a corner that Süle eventually manages to clear. Germany need to ride this early wave of pressure.

Not far away!

Lovely football from Germany as Sané skates inside and feeds Musiala. He helps it on for Wirtz, whose shot is blocked by Ochoa in the Mexico goal.

Führich in the zone
Stuttgart's Chris Führich is one of three new faces in the current Germany squad. The Stuttgart attacker, who is the Bundesliga's top assister so far this season, made his debut in the second half against the USA. "It's an unbelievable feeling to have made this step, I can't really describe it," the 25-year-old said afterwards. "Playing for Germany was a dream I've had since I was a kid, and now it's come true. I'm grateful that I am where I am now. When you reach your goal, you're happy."
The contest has been put back by 15 minutes due to traffic issues in and around the sports complex where the stadium is based. NHL team Philadelphia Flyers and baseball's Philadelphia Phillies are also in action today, so you can imagine how busy the place is!
Nagelsmann's take on debut win over the USA
"I'm looking forward to the next step. I’m pleased for the team that there is positive feedback. It was important that we have a certain aesthetic quality to our game. This looked good today, we played sensible and passionate football. The basic thing for me it that they have fun. The national team is not an everyday thing, but something to be passionate about, that’s what I want to see and that was good. It would be nice if this run continued – and finishing with a happy ending would be even better."
Two changes
Nagelsmann switches out Dortmund duo Mats Hummels and Niclas Füllkrug, with Niklas Süle and Thomas Müller their replacements in the only changes to the USA win. BVB head coach Edin Terzic will be happy about that, with the Black-Yellows hosting Bremen in the Bundesliga on Friday.
The Mexico icon made a huge splash in the Bundesliga after joining Bayer Leverkusen in 2015. Now at LA Galaxy, he will play no part in today's game, but his impact was such that he remains a popular figure in Germany's top flight.

Führich has been in top form for high-flying Stuttgart this term. Have a look at his goal contributions to remind yourself why he was called up to the Germany squad for the first time.
Germany team news
Nagelsmann, meanwhile, may rotate as he tries to find a good balance. Joshua Kimmich is the only player guaranteed not to play, as his illness has forced him to leave the camp early. Chris Führich, who came on as a substitute for his debut against the U.S, could be included in the starting XI, while Kevin Behrens could earn his first cap.
Manager Jaime Lozano should field a strong side against Germany as he continues to get a feel for his squad following his appointment earlier this year. Santiago Giménez is the team's danger man, having already scored 12 goals for Feyenoord this campaign, while Hirving Lozano, Edson Álvarez and Raúl Jiménez are others who could cause Nagelsmann's men problems.
Mats Hummels and Thomas Müller are back in the same Germany squad for the first time since 2021. Although both featured against the USA, they weren't on the pitch at the same time. The two are good friends, as you can see in this video.
Head-to-head
These two nations have faced off 12 times in the past, with the first meeting coming in 1968 (a 0-0 draw). Germany have the upper hand, having won on six occasions to Mexico's two, but the latter were victorious in the most recent match-up, prevailing 1-0 in the group stage of the 2018 World Cup.

Mixed form for Mexico
The North American nation have struggled to find consistency over the last year. They are currently unbeaten in their last six matches, which includes a Gold Cup final victory. However, they failed to make it out of the group at the 2022 FIFA World Cup, while the 3-3 draw with Uzbekistan last month was a disappointing result.
Winning start for Nagelsmann
Julian Nagelsmann kicked off his reign as Germany manager with a 3-1 victory over the USA on Saturday. The four-time World Cup winners fell behind to Christian Pulisic's fantastic opener, but goals from İlkay Gündoğan, Niclas Füllkrug and Jamal Musiala secured the win.
