Next Sunday sees the top four go head to head, and Wenger believes it could prove to be a turning point in the race for the title.
"It will be very interesting because we go to Chelsea and Manchester United plays Liverpool as well, so we will have a better idea next Sunday night as to what will happen until the end of the season," he said.
"Chelsea is a big game for us now, but maybe it's a good opportunity not to put too much pressure on ourselves and to show how good we are against a good side."
