Pierre-Emerick Aubameyang was back at training with Chelsea.
The striker, 33, was dramatically axed from the club's Champions League squad on Friday and left out of the matchday 18 which drew 0-0 at home to Fulham that evening.
The Sun says the brutal chop last week only strengthened claims from Spain that Aubameyang could go back to the Nou Camp.
He is six months into a two-year contract at Stamford Bridge, with the club holding the option of a third year.
The Gabon international, who had his contract terminated at the Gunners by mutual consent after a string of misdemeanours and poor time-keeping, was given a weekend off by Chelsea boss Graham Potter as consolation.
