French defenders Sebastien Squillaci and Laurent Koscielny and Moroccan striker Marouane Chamakh have all come into the Gunners squad and made an impact so far and Wenger is confident they can continue that against Braga in the Champions League opener tonight.
"It's a big test for them. We can't afford (any adaptation period). But Squillaci is 30 years old and Chamakh has already shown what an important player he can be for us," he said.
"He scores important goals. He doesn't score the 4-1, he scores the 2-1, the 1-1 equaliser in most of his games. Koscielny's the only one who's had no time to think about the adaptation - he's just had to play. Until now I believe he's doing well."
