Chelsea finished outside the top four last season, as Antonio Conte’s side ended in fifth spot, 30 points behind Manchester City at the top.

But the Blues are cruising this season, with a perfect start to the season after four games. Despite Chelsea’s start to the season, Gunners legend Paul Merson doesn’t think Chelsea can win the title due to our defence.

Merson says he cannot see Chelsea challenging for the title despite their perfect start to the season with such a defence and pointed out that David Luiz is a mistake waiting to happen at the back.

He told Sky Sports: “I’m a Chelsea fan and I cannot see them winning the league one bit. I think, attacking wise, they are great. But that back four, I don’t think they can win the league with that back four.

“David Luiz will do something. He needs to be playing in a back three in my opinion. You only have to look at the Newcastle game.

“They’re cruising and only he knows what he was doing when he went to the head ball. He just waited for it, I don’t know what he was trying to do.

“[Marcos] Alonso plays where he wants to play, he’s got no position, he just goes and plays. When they play against the big boys, they’ll get picked off.

“There’s a lot of work to be done even though it’s a great start. If Chelsea finish in the top four, I think they’ve had a great season.”
