Wenger's side were on their best behaviour for the 3-2 victory against Newcastle last Friday and Lekcetho said: "We saw what happened at Old Trafford and know that football is an emotional business. I don't think they will behave like that any more and we are expecting a more peaceful game.
"Arsenal have experienced players and they know how to behave. I don't think it will be as harsh against Lokomotiv, but it will be a difficult game.
"We usually start a bit slowly in the Champions League but we play well as a team with quick, passing football and we need to win this game if we are going to qualify for the next stage."
