AS Roma are set for a row with Barcelona over the minimum fee release clause of Arsenal target Antonio Sanabria, according to Spanish publication Sport.
The 17-year-old striker - who has reportedly turned down the Gunners in favour of a move to Stadio Olimpico - is at the centre of a transfer tug-of-war between the Spanish and Italian giants.
Roma insist that Sanabria's clause is set at €3million, but the Catalan club claim it's increased by four times that figure to €12million, after he became a Barcelona B player.
Camp Nou officials allegedly contacted the Paraguayan youngster's agent before he featured for Barca's second string, but the problem lies where they couldn't officially change the clause until the transfer window reopened.
The €9million discrepancy could put pay to Sanabria's switch to Serie 'A', and allow Arsenal boss Arsene Wenger another chance to lure the talented teenager to the Emirates Stadium.
For months it looked like the South American starlet would follow the likes of Cesc Fabregas, Fran Merida, Hector Bellerin and Jon Toral in swapping Barcelona for north London.
However, the Daily Mail reported on Wednesday that Sanabria had opted to join Rudi Garcia's Italian revolution, having not been afforded any first-team opportunities in Spain under Gerardo Martino.
