Chelsea and Manchester City are both tracking defensive midfielder Mehmet Topal, according to The Daily Mirror.
The 25-year-old joined Valencia from Galatasaray during the summer, but with a £10 million buy-out clause attached to his contract, clubs are beginning to circle.
Chelsea and City, two of the Premier League's big spenders are both expected to be interested.
Chelsea may be tempted to bring in Topal, given the long term injury to Michael Essien and the loss of form of John Obi Mikel.
City, who brought in Owen Hargreaves during the summer, have a plethora of options at the middle of midfield, however Roberto Mancini's insistence on playing three in the middle of the park means injury to either Gareth Barry, Yaya Toure or James Milner, leaves them short of genuine quality.
Furthermore, with rumours circulating that Nigel De Jong is target for Real Madrid, City may be forced into bringing in a replacement.
Both Chelsea and City would be able to offer Topal Champions League football, if as expected they both finish in the top four in the Barclays Premier League.
