There's concern inside Barcelona that Neymar has become increasingly unsettled over the last 12 months.
Sport says during his extended summer break, Neymar has listened more attentively to the offers tabled than in previous years - news which has reached the Barca boardroom.
Manchester United boss Jose Mourinho has been in regular contact with Neymar and his father since November, while PSG, Manchester City and even Real Madrid have also made it clear they're prepared to meet his €200m buyout clause should the Brazilian be willing to leave.
Just last week, Neymar poured fuel on the fire when, at home in Brazil, he stated: "Who knows about tomorrow? I am settled, but anything can happen, who knows? "Manchester United? Yes I could go there - or I could go to Eibar!"
Neymar's current deal, signed in October, runs to 2021.
