Following the case against Chelsea where Chelsea have been banned from signing any players for the next two transfer windows, another Premier League club have had a complaint lodged against them.
This will be the third PL club in quick succession to have a complaint logged against them but only the second where FIFA have got involved.
It is understood that FIFA have confirmed they are investigating the signing of Jeremy Helan by Manchester City from Rennes.
Helan, now 17, transferred from Rennes when he was just 13. Rennes claim this transfer is more serious than Chelsea's signing of Kakuta, the French midfielder whose move lead to the club's transfer ban.
Where Kakuta had the possibility of a formal contract in place, Rennes claim that Helan had signed a pre-contract and as soon as he featured for the France youth set up he was officially a Rennes player.
If found guilty Manchester City face the possibility of a lengthier ban than Chelsea for their transfer dealings.
