Manchester City boss Roberto Mancini wants a deal for Cagliari midfielder Radja Nainggolan.

The Belgium international, who boasts an Indonesian background, is a favourite of Mancini's, says La Repubblica, and the City manager would sign him immediately if possible.

Cagliari are reluctant to sell in January and would prefer to wait until June.

However, an offer of £12-15 million would be enough to convince the cash-strapped club to part with the 23 year-old.
