West Ham were convincing winners themselves, ending their pre-season trip to Austria with a 3-0 win over Karlsruhe SC.
Hammers boss Bilic said: “It was a good test for us, in a good atmosphere against a good team who play in the second Bundesliga.
“They are starting on the first weekend in August, so already they have been in pre-season for a long time.
“It was a good game, and we expected that to be fair. We expected to have hard legs in the games we have played so far, and we expected to be a little fresher for this one.
“We were, and we played some quality football. We played as a team, we were compact, we saw some great things and it was a good result.
“The only downside of this game is that we have to see what is [wrong] with Cresswell. He got injured and it didn't look that good. We will have to assess it."
