Arsenal are reported to have told Barcelona it will cost them £38.6million if they wish to re-sign Hector Bellerin.
Barca officials have confirmed they are keen to take Bellerin back to the Nou Camp, but they will have to break the bank to have any chance of doing a deal.
Reports in the Spanish press suggested that Barca were hoping to do a deal for £30million, but Gunners boss Arsene Wenger will hold out for closer to £40million.
Arsenal will only be willing to do a deal at the end of the season when they have more time to draft in a replacement, but Barca could chance their arm in the January window.
Bellerin is known to be happy at the Emirates Stadium, but a chance to return to Barcelona will no doubt appeal and the Gunners could face a fight to keep hold.
