Arsenal have saved £7million on the cost of signing Mesut Ozil, leaked transfer documents reveal.

Ozil was signed from Real Madrid in the summer of 2013 and it was widely reported that the transfer fee was €50million, equivalent at the time to £42.4million.

But the website Football Leaks has published fine detail of the deal, which demonstrates that because Arsenal’s club-record transfer is structured in Euros, they have saved a potential £7million.

When Ozil made the switch to north London, the Premier League club had agreed to pay Real an initial fee worth £33.4million (€44million), with a further £760,000-a-year (€1million) for every year up to six that Arsenal qualify for the Champions League with the midfielder still at the club.

Arsene Wenger’s team have qualified for two Champions League campaigns since Ozil has been at the club, which means they have paid £35million in total for the Germany playmaker to date.

The fee is likely to rise as Ozil is close to agreeing a contract extension with the Gunners but the leaked document demonstrates the saving made by Arsenal.

In an intriguing twist to Ozil’s future plans, it reveals Real Madrid negotiated a first-option La Liga clause in the deal that took the attacking midfielder to Emirates Stadium.

The transfer agreement states that Real have a 48-hour buy-back option if Arsenal agree to sell Ozil to another Spanish club.

The Londoners must notify Real of any offer from a Spanish club and then give them two days to match the terms contained in the offer to Arsenal.

In addition, the Spanish giants have negotiated a 33 per cent cut of any transfer fee over the £38million (€50million) they sold Ozil for two-and-a-half years ago.

Germany World Cup winner Ozil is enjoying comfortably his best season for Arsenal since joining the club, and is regarded as one of the front-runners to be crowned the Player of the Year.
