Arsenal are regarded as the front-runners to sign Philippe Coutinho from Barcelona during the ongoing transfer window.
The Brazil international spent the previous season on loan with Bayern Munich where he won the treble under manager Hansi Flick.
However, he is expected to return to the Camp Nou for pre-season training after Bayern decided against triggering the £105m buy option.
According to Don Balon, Coutinho could be one of the players leaving the Blaugrana as new boss Ronald Koeman aims to reinforce the squad.
The 27-year-old is said to favour a return to the Premier League and it is claimed that the Gunners are the firm favourites to sign him.
It remains to be seen whether the Blaugrana will accept the proposal.
