Manchester City have jumped to the front of the queue in the race to to sign Porto's highly rated Eliaquim Mangala, reports the Express.
Manchester United were thought to be keen on the French international after the club's scouts were sent to Portugal to keep a close eye on him.
However, David Moyes is yet to make an offer Mangala, instead concentrating all of his efforts on brining a midfielder to Old Trafford
Jose Mourinho is also thought to be a long term admirer of the defender and is keen to bring him to Stamford Bridge.
However, with the news that Vincent Kompany could miss up to a month through injury and after City's poor defensive display against Cardiff, Manuel Pellegrini is ready to trigger Mangala's £38m release clause.
According to French paper L'Equipe, City have opened talks with the Portuguese champions over the 22-year-old.
However, Mangala remains unconvinced by the project at the Etihad stadium and may wait for Chelsea or United to come in for him.
There are also concerns on where Mangala would sit in the City squad once Kompany returns to the squad.
In the meantime, City are expected to complete a deal for veteran Martin Demichelis as Pellegrini looks to increase his options in the heart of the Citizen's defence.
