Manchester United legend Roy Keane says Carlo Ancelotti faces a huge challenge at Everton after their 4-0 thrashing by Chelsea.

Ancelotti has overseen significant improvements at Everton since succeeding Marco Silva in the role.

But the display against Chelsea shows there is still plenty of work to be done.

“We all like nice football but tackling is part of the game with the physical side and Everton, I think this is the toughest job for Ancelotti that he will ever have ," Keane told Sky Sports.

“I bet he's been left scratching his head.

"People said they've turned a corner in the last few months and they're going to be a threat for Europe, forget about it, they're way off.

“They were so short. You always think about Everton being aggressive but if you're not aggressive out of possession, you're in big trouble."
