Freiburg had finished second to West Ham in the group stage, before winning a dramatic play-off against Lens to reach the knockout rounds. The hero of that tie, Roland Sallai, very nearly gave his team the lead inside the opening 60 seconds, but his goal-bound effort was blocked by Vladimír Coufal. Freiburg continued to set the tempo, with Sallai pulling the strings. The Hungary international set up a promising opening for Lucas Höler with 31 minutes gone, but the Freiburg forward could not find a way past Łukasz Fabiański in the West Ham goal. The visitors responded in kind, with Jarrod Bowen crashing a volley wide.
Freiburg were unlucky not to go ahead early in the second half as Fabiański stopped a deflected Sallai scissor-kick from creeping in. That sparked a wave of West Ham pressure, with Konstantinos Mavropanos heading against the crossbar from a corner and Lucas Paquetá failing to turn Mohammed Kudus's teasing cross into the six-yard box on target. Noah Atubolu kept out well-struck efforts from James Ward-Prowse and Bowen, who miscued from close range soon after. It proved a costly miss as Gregoritsch pounced at the other end to convert Sallai's cross-shot and give Freiburg the edge heading into the second leg in London on 14 March.
Match stats
Freiburg are playing in UEFA competition for the sixth time.
Gregortisch scored his fifth Europa League goal of the season.
Sallai produced his first assist in this season's competition, adding to his four goals in the previous rounds.
Christian Streich oversaw his 478th competitive game as Freiburg coach.
Mavropanos made 80 Bundelsiga appearances as a VfB Stuttgart player and also represented Nuremberg in the German second division.

Full-time: Freiburg 1-0 West Ham
There goes the final whistle! Christian Streich's super sub Michael Gregoritsch once again comes up trumps late on for Freiburg, who scored against the run of play to take a valuable 1-0 lead into next week's UEFA Europa League Round of 16 second leg against West Ham!
Would you believe it!? Freiburg have only gone and taken the lead against the run of play and it's that man Michael Gregoritsch - Mr. Super Sub - who has scored. The Austrian has the simplest of tasks to slot home from close range from Sallai's cross-shot across the face!
Another big stop from Atubolu to deny Bowen, who almost found the left corner of the goal with a smart shot.
Visitors taking control
Christian Streich's side have seen West Ham take the upper hand in this game in the past five minutes or so. The home fans are doing their best to inspire a response from the team in red and white.
This is a very dangerous spell from the Premier League side and Bowen is the latest player to have a go at goal, his curling effort well saved by Atubolu between the Freiburg posts.

More on those teams
Freiburg are unchanged from the 2-2 draw against Bayern, with Christian Günter and Vincenzo Grifo among the starters. West Ham show one change, though, with Łukasz Fabiański starting in goal as he has throughout the London club's 2023/24 Europa League campaign.
Freiburg have made the last 16 of a European competition for the second time in their history following their elimination by Juventus at this stage of last season's UEFA Europa League.
Another big atmosphere in store
European nights seem to bring out the very best of Freiburg's new stadium. The place was positively rocking in their comeback win against Lens in the last round. Freiburg's head of football Jochen Saier said after the match: "It was incredible. I have never seen the stadium like that. After our first goal went in, the energy was unbelievable."
More from Freiburg
Recently recovered from an achilles tendon problem, Matthias Ginter is back to 100 per cent and is expected to feature prominently for the Black Forest side in European competition this week. Of opponents West Ham, the 30-year-old said, "Sure, they have a good team with a lot of good individual players. It will be important that we defend well. We are all competitive athletes and always want to get the most out of [games]. That's why we'll try to make it a special evening [against the Premier League side]."
West Ham midfielder James Ward-Prowse said he is expecting Freiburg to provide a much sterner test to when the teams met in the group stages earlier this season. “It’s certainly not going to be an easy ride," the 29-year-old explained, in quotes appearing on the club's official website. "It’s probably going to be tougher than when we’ve played them before, because they know a bit more about us now, and they’ll have extra motivation going into the tie," Ward-Prowse added.
Freiburg boss Christian Streich is determined his side give it a real go against West Ham, using last weekend's 2-2 draw against Bayern Munich as an example of the fight his side is capable of. "We are in the round of 16, we fought hard for this and we are very happy now because it is something very special for us," the tactician explained. "But of course you always want more. What's important for us is that we are courageous, like we were against Bayern."
Freiburg are boosted by the return to full fitness of captain and left-back Christian Günter, who marked his first start since Bundesliga Matchday 1 with the opening goal against Bayern. However, Philipp Lienhart - one of Streich's first-choice central defenders - is still unavailable due to a groin injury. West Ham, meanwhile, make the trip without injured midfielder Maxwel Cornet.
Freiburg showed tremendous fighting spirit to reach the last 16 proper. Following a goalless play-off first leg in Lens, Die Breisgauer were 2-0 down at half-time in the return fixture. Roland Sallai reduced the arrears with over an hour gone, before levelling the tie in stoppage time. An extra-time goal from Michael Gregoritsch sealed the comeback and set up a rematch against West Ham. It was the Hammers who topped Group A ahead of Freiburg, thanks to home and away wins over the Black Forest outfit - Freiburg's only European defeats in 2023/24.
UEFA Europa Conference League holders West Ham are also in the mix for another season of European football. David Moyes' team were on an eight-game losing run in all competitions, but head to Freiburg in seventh place domestically after back-to-back wins over Brentford and Everton.
