Chelsea have reportedly joined Manchester City in pursuit of Malaga midfielder Isco, and a bid could be made for the Spain international during the January transfer window.

Arsenal and Manchester United have also previously been credited with interest in Isco but, according to AS, Chelsea and Manchester City are now the leading contenders to sign him.

Isco has an enticing €21 million buyout clause written into his contract with Malaga, although the 20-year-old's employers hope to agree a new deal with the playmaker to take this fee closer to €40 million.

Chelsea, though, may reportedly make their move before Malaga can tie Isco down on improved terms, with Blues owner Roman Abramovich keen to acquire further attacking midfield reinforcements.

The signing of Isco would be very much in keeping with Abramovich's recruitment in recent times, with the likes of Juan Mata, Oscar and Eden Hazard all in a similar mould to the Spaniard.

Manchester City, however, are reported to be lining-up a bid for their own for Isco as Roberto Mancini makes plans to bring fresh blood to the Etihad Stadium in the January transfer window.

Mancini has, though, denied he is interested in Inter Milan star Wesley Sneijder, as Manchester City already have the likes of David Silva and Samir Nasri among their number.
