LONDON: UEFA is concerned that Real Madrid and Manchester City have distorted the transfer market in Europe by paying big fees for new players and high wages.

Backed by their wealthy Abu Dhabi owners, Manchester City are still spending despite having paid about 100 million pounds ($170 million) for Carlos Tevez, Roque Santa Cruz, Gareth Barry, Emmanuel Adebayor and Kolo Toure.

With Real Madrid having spent 160 million pounds ($271 million) on Cristiano Ronaldo, Kaka and Karim Benzema, other clubs are struggling to compete for new players - a situation that is displeasing European football's ruling body.
