"It's very tight at the top, Liverpool are in the race as well, and they have an advantage as it is the only competition they play," said Wenger.
"I hope it will be tight until the end, because then it will be interesting and if you are consistent then you have a chance to win.
"You need to be at your best to find the resources to win games, this is a big game for us and of course this weekend we just want to focus on the three points.
"We got the three points against Sunderland who are a tricky team, so we want to do it again.
"We have to look at our results, just focus on that and not speculate too much because we're in a period where we have to move forward."
