Arda Turan joins Barcelona with a cloud over his move from Atletico Madrid.
The Turkey international joined Barca yesterday for a fee of €34 million, rising to €41 million.
However, as it was done without a club president in place, a clause was included which could see Turan sold back to Atletico for a discounted €30.6 million.
While the deal has the support of leading candidate Josep Maria Bartomeu, should another man win the July 18 election, there is every chance Turan could be offloaded back to Atleti, says Sport.
The clause will expire on July 20 - leaving the next president 48 hours to make a decision.
