The 24-year-old appears to have been given a new lease of life under the Italian coach at Stamford Bridge after Sarri was appointed as Antonio Conte’s successor at the west London club back in July.
The England international has scored three goals and made three assists in nine Premier League appearances so far this season and has also notched up one assist in the Europa League.
Barkley’s recent form has been particularly impressive, with the former Everton man having scored two goals and made two assists in his last two outings for the Blues.
The midfielder had initially made a slow start to life at Stamford Bridge after joining from Everton in January, but he appears to be finding his feet under new Chelsea FC boss Sarri.
And the Chelsea FC manager has expressed his delight at how Barkley has been developing under his guidance in recent months.
Speaking at a news conference at Cobham on Friday ahead of Chelsea FC’s clash with Crystal Palace on Sunday, Sarri said: “In the first week [of Sarri’s time at Chelsea FC], I saw some matches of Chelsea and some matches of Everton, because I wanted to see him on the pitch.
“He has great technical quality, he has great quality from a physical point of view – he is improving since his injury last season – and he has improved from the tactical point of view.
“He is becoming a very, very important player for us, and not only us, for the English people too.”
Chelsea FC will host Palace on Sunday afternoon looking to preserve their unbeaten start to the season in the Premier League.
The west London side finished fifth and won the FA Cup last term before Conte was sacked in the summer months.
