They believe the 24-year-old central defender could be entering his final days as a Barcelona player, given the wealth of interest and of course, a very appetising release clause value of just €12 million. This clause was triggered because Bartra didn't make fifty appearances during the 2014-15 campaign.
Forced to play second fiddle to the likes of Pique, Mascherano and Mathieu, the return of Vermaelen to fitness and action, also casts doubts on whether Bartra will remain at the Camp Nou this summer.
Although it is suggested Barcelona are keen for Bartra to stay, the player and his agent have already raised doubts about that, given there are a host of clubs ready to pounce.
Sport have previously claimed that Manchester City, Bayern Munich and Borussia Dortmund have already declared their interest, whilst Inter Milan, Liverpool and Tottenham Hotspur, have also made discreet enquiries.
On Monday, it is believed a meeting is due to be held between Bartra and the club, which could prove decisive in whether or not he remains at Barcelona. Luis Enrique has already reportedly called him, to offer assurances of more games and insist he stays put.
The key to all of this is that from 1st July, the clause valuation raises once more from €12 million to €50 million, which would indicate that if Bartra is still at the Camp Nou beyond this date, he will likely remain there during the 2015-16 season.
In the meantime, if any club lodges the €12 million at the LFP head offices of La Liga, there will be no further room for Barcelona to negotiate. The player will be clear to move elsewhere. The clock is ticking.
