Pascal Gross has urged Albion to keep their wits about them for 90 minutes and beyond against Manchester City.
The summer signing knows what it is like to face a Pep Guardiola side after playing home and away for Ingolstadt against Bayern Munich two seasons ago.
But it is his experience from big home tests last term, when Guardiola was already at Manchester City, which will ensure he works hard to stay physically and mentally fresh right up until the final whistle.
Ingolstadt remained on level terms at home to Bayern for 90 minutes but were then sunk by injury-time goals from Arturo Vidal and Arjen Robben.
They led 2-0 and 3-1 when they hosted Borussia Dortmund. But a tense finale was in store when Dortmund got back to 3-2 and they nicked a leveller right at the death.
Ingolstadt also led Werder Bremen 1-0 and 2-1 until conceding three goals in the last ten minutes to lose 4-2.
So nothing can be taken for granted, even if Albion are on course for a famous result as the fourth official raises the board.
He told The Argus: “We always did well with Ingolstadt against the bigger teams.
“Last year we were 3-1 up on Dortmund but ended up drawing 3-3. They scored in the last minute. Bayern in 90 minutes was 0-0.
“In every football match you have a chance, even against the best teams in the world.

Ingolstadt lost 2-1 at home to Bayern and 2-0 away two seasons ago, when Guardiola was in charge.
From what he saw in those games, Gross believes Albion can allow City some possession – up to a point.
City led the Premier League possession and pass completion stats last season with figures of 61% and 85.5% respectively. Those numbers changed very little whether they were playing…
