Paris Saint-Germain are the latest club to register their interest in signing Manchester United midfielder Marouane Fellaini and are reportedly willing to offer the Belgium international a four-year contract as they look to bolster their defensive midfield options.

Fellaini has less than 12 months left to run on his current contract at Old Trafford and is seeking assurances over game-time before he commits his future to Jose Mourinho's side. The former Everton star was close to moving away from Manchester in the summer transfer window but Mourinho blocked the 30-year-old's move to Galatasary, saying that it would be easier to prise him away from Old Trafford than Fellaini.

Mourinho may have prevented Fellaini from leaving United a few months ago, but the Portuguese coach will not be able stand in the Belgian's way next summer if a contract is not signed. Along with Galatasary, Turkish giants Besiktas and Serie A duo AC and Inter Milan have all been credited with an interest in the midfielder, while Ligue 1 leaders Paris Saint-Germain have made a "concrete approach" to Fellaini ahead of a prospective summer switch, according to Le10 Sport.

PSG are blessed with an embarrassment of attacking riches but their holding midfield options are scant in comparison. Unai Emery's men tried to pilfer Fabinho from current champions Monaco in the summer but their failure to land the Brazilian has left them light in the centre of the park, with Adrien Rabiot, Marco Verratti and the ageing Thiago Motta the only esteemed options for the French outfit's engine room.

Their want for further defensive reinforcements combined with their need to comply with Financial Fair Play requirements has led them to pursue Fellaini; the Parisians are already in discussions with Fellaini's representatives and are not worried by the Belgian's potentially vast wage demands due to the lack of transfer fee required. PSG could tie down United's wrecking ball in January if they so desire; players can sign pre-contractual agreements with foreign clubs during the winter transfer window ahead of a free transfer in the summer.

United are still hopeful of thrashing out an agreement with Fellaini, who turned down a new contract in September, but their immediate focus rests on their upcoming clash against high-flying Brighton and Hove Albion at Old Trafford on Saturday.
