Manchester City will have to pay a £3 million sell-on fee to Atletico Madrid should they choose to cash in on striker Sergio Aguero, Goal.com can reveal.
It is part of the £38million deal agreed between City and Atletico when Aguero moved from Spain last summer.
City paid £35m to land their record signing but there is a clause in the agreement stipulating that the Premier League club have to pay a further £3m to the Spanish team when they sell the Argentine.
Sources have told Goal.com that Atletico insisted upon the clause when the two clubs were negotiating the Argentine’s transfer last August.

This makes it even more far-fetched that City would off-load a player who has had an impressive debut campaign in England, scoring 24 goals in 41 matches in all competitions.
City moved quickly on Tuesday to deny reports in Spain that Aguero is unsettled in Manchester and keen to move to Real Madrid this summer.
While the City futures of striker Carlos Tévez, Mario Balotelli and Edin Dzeko - as well as on-loan pair Emmanuel Adebayor and Roque Santa Cruz, are uncertain - with all three available for transfer this summer, senior club officials will not entertain the prospect of selling Aguero.
The 23-year-old is regarded as low maintenance and professional by staff at Etihad Stadium, a far cry from the never-ending controversies surrounding Balotelli and Tevez.
There is, however, genuine interest from Real in unsettling a player who the Spanish giants tried to prise from across the city last summer.
Aguero says he hopes to return to action for City on Sunday for the match at Arsenal after missing the club's last two games with a foot injury.
