Graham Potter reveals key reason behind Pierre-Emerick Aubameyang’s sensational Chelsea form after stalling at Arsenal

GRAHAM POTTER reckons that Pierre-Emerick Aubameyang's blistering Chelsea form has been a result of improved fitness levels.

The former Arsenal captain, 33, signed for the Blues from Barcelona late in the transfer window.

He initially joined to reunite with his former Borussia Dortmund boss Thomas Tuchel - but played just an hour for the German before he was sacked by new owner Todd Boehly.

But Aubameyang has flourished since the arrival of Potter - bagging three goals in four matches under the former Brighton gaffer.

Following the Gabonese striker's latest effort in the 2-0 win over AC Milan on Tuesday, Potter was asked if he could take any credit for the striker's form.

The 47-year-old modestly replied: "No, we’ve not done anything special, it’s all down to him.

"He has been building his fitness up. He had a difficult summer.

"So it’s been a case of building up his match minutes. The more he gets, the stronger he gets... and the more we understand him, the more he understands us.

"Everyone knows his quality and it’s great for him. He looks like he is enjoying his football and scoring goals is important."

Aubameyang bagged Chelsea's second goal of the night, expertly converting Mason Mount's smart pass after Jorginho had given the Blues the lead from the penalty spot.

The night was a special one for Aubameyang, who played in Milan's academy without ever breaking into their first team.

"Another great team performance come on Chelsea."
