Chelsea midfielder Ross Barkley has revealed how Blues manager Maurizio Sarri has improved him at Stamford Bridge since taking over the reins from Antonio Conte in the summer.

Barkley, who joined Chelsea from Everton during the winter transfer window last season, has enjoyed a better run of form on the back of a strong pre-season under Sarri this term.

The Englishman has returned to his best shape, having notched up 28 appearances in all competitions, and earned himself a recall to the England national team earlier in the season.

In the wake of resurrecting his career at Chelsea after a torrid spell with injuries at Everton, Barkley has revealed how Sarri has transformed him at Stamford Bridge since arriving in the summer.

Barkley admitted he is more tactically aware of his responsibilities under Sarri and went on to reveal the Chelsea boss showed the squad clips of Napoli under him to give them an idea of his style.

“I look at things more tactically”, Barkley told the Chelsea magazine.

“Understanding about arriving in the box at the right time, or if the balance is not right on the pitch to maybe not make the run into the box at this time.

“In pre-season, just to get an understanding, he’d show us a few clips of his Napoli side doing the movements and the tactical work that we do now – just introducing the way he wants us to play to eventually be the best team in Europe.”

Barkley, who has a contract with Chelsea that runs until 2023, has been directly involved in seven goals so far this season.
