Wilshere has now praised the high-flying Merseysiders for their impressive style of football under new manager Roberto Martinez.
"I'd say [Everton have been our toughest opponents this season]," he told the club's official website. "We played Tottenham here as well which was a tough game, but Everton always come here and they do well.
"They're a strong team, they've got a new manager as well so they play a different way but they're still just as strong. They took the game to us in the first half."
