Former Chelsea striker Tony Cascarino is unimpressed by Antonio Conte's current team.

The Blues lost a league match against Arsenal for the first time since 2011 on Saturday as Arsene Wenger's side romped their way through a disorganised defence on their way to a 3-0 half-time lead that they maintained with ease in the second period.

“Chelsea's problems run far deeper than they first appeared to," Cascarino wrote in his Times column. “Thibaut Courtois, the goalkeeper, is playing like he wants to get away, Cesc Fàbregas has been linked with a move and Eden Hazard has not been at the races for a while, apart from a couple of good games here and there.

“And then there's the back four — it's been disastrous. It's not been upgraded for the past 18 months and they are a shadow of the defence that helped Chelsea win the league title in 2014-15. Gary Cahill is out of sorts, while César Azpilicueta is nowhere near the level he was a couple of seasons ago.

"The worst thing about David Luiz, who was a panic buy from Paris Saint-Germain and is only playing because John Terry is injured, is that he plays everyone onside because he sits so deep. It creates so much space and Arsenal exploited that.

“Chelsea look like a mid-table team at the moment. The only team they have beaten and looked like worthy winners against is Burnley in the league at Stamford Bridge. The defence was the one key area they needed to strengthen in the summer and they didn't address that properly."
