Five extra minutes added onto the 90.

And it's time for the substitutions, including American defender George Bello.

Hamburg dominated the shot count before the break by 9-2. Now it's 5-3 in Bielefeld's favour just 10 minutes into this half.

Neither coach sees the need to change their team for the second half.

Bielefeld find themselves 1-0 down at half-time for the fourth game in a row. The last time they turned around a deficit after 45 minutes was in January 2019 away at Dresden (4-3 after 3-1). HSV have won their last seven league games when leading at the break. It's 33 games unbeaten with a half-time advantage (W23, D10).

Jeers ring out from the home support as the half-time whistle goes. They've struggled to get into this one. Admittedly, they have limited HSV to little in terms of clear-cut chances but one telling mistake has allowed the visitors to claim the advantage.

It's over 30 degrees in Bielefeld today so we'll have a one-minute break for drinks and a quick tactical discussion.

Bielefeld captain Fabian Klos gives a lengthy pre-match pep talk to the team as they gather in a circle before kick-off. Can they get on the board today?

By no means a rare occurrence in Bundesliga 2, but this game is a sell-out, including around 3-4,000 travelling HSV fans, as the SchüoArena rises to its collective feet in song before the teams emerge.

Hamburg top the division for possession with an average of 63 per cent – Bielefeld are 12th with just 48 per cent – and it all starts at the back for Die Rothosen, where captain Sebastian Schonlau has completed 94 per cent of his passes and central defensive partner Mario Vuskovic comes in even better at 96 per cent. They are the top two in the league for completion rate out of all players who have made at least 75 passes.

Although Bielefeld have conceded seven times, their new centre-back from Heidenheim – Oliver Hüsing – has proven he’s one of the most difficult defenders to get past in Bundesliga 2, winning 42 out of his 52 challenges. His 81 per cent success rate is the best of all players in the division.

HSV have conceded just once over the first three matchdays, compared to five at the same stage last season. It means they’ve amassed six points from scoring just three goals. They had previously always netted at least six times over the first three games of a Bundesliga 2 campaign. And the stats show they could have and probably should have scored more, with an xG value of 5.1.

This is the third time Bielefeld have started a Bundesliga 2 campaign without a point after three games (after 1987/88 and 2010/11). On each previous occasion they were relegated by finishing bottom. However, they picked up their first points on Matchday 4 each time. In 1987 they drew 0-0 with Rot-Weiss Essen, and it was a 1-0 win over Ingolstadt in 2010. The class of 2022 will want to avoid making unwanted history today.

This is the club's 750th game in Bundesliga 2. They are the 12th club to reach that milestone.

"It's about force and energy in Bielefeld. That's the only way you can get a result there. It'll be tough, even if Arminia haven't won a point in their first three league games. That have lots of individual quality."

"HSV have had a better start than us - we can say that. We hope we can take advantage of their not so good periods at the weekend. In terms of tactics, HSV like to take the game in their hands. That suits us."

Both sides are unchanged from their games last week.
