Sky Sports pundit Paul Merson has backed Chelsea to challenge Liverpool and Manchester City for the Premier League title this season.

The Blues had a poor start but have been in great form lately, coming from behind to beat Sheffield United 4-1 last weekend.

Merson believes they have what it takes to go for the Premier League title this season.

“If we are going to talk about Tottenham winning the title, then Chelsea are right in the mix,” he told Sky Sports, as quoted by Football 365.

“If Spurs can win it, then for sure, Chelsea can win it. Frank Lampard has now got who he wants in key positions and you can really see the difference.

“Thiago Silva is world-class. They’ve got two full-backs who are as good as any in the league and for me, they are the two England full-backs, in my opinion. They are outstanding. Silva is also only going to make Kurt Zouma a better player and the goalkeeper Edouard Mendy is solid.

“I know Sheffield United are down at the bottom at the moment, but they are a hard team to play against. They are organised and when you go 1-0 down, you know it’s going to be a difficult evening.

“However, they literally dismantled Sheffield United. They made them look like a proper relegation team, which I don’t see that because I think Sheffield United will be okay this season. They made them look distinctly average and that’s a sign of a good team.”
