Everton could move into the top four themselves with victory tonight and Wilshere is expecting another tough test.
"Everton are a very good team," Wilshere told arsenal.com. "It's an especially hard game when you go to Goodison Park, but even when they come here you know what you're in for.
"They've got good players, can hit you on the counter-attack, have a strong midfield and are hard to break down. They are four points behind us, so it's massive that we come into it after winning on Saturday."
