Manchester United are joining the battle for Roma midfielder Radja Nainggolan.

Gazzetta dello Sport says the midfield enforcer still hasn't agreed a new contract and United are ready to strike.

The Belgian ace was promised a pay rise by the Rome-based outfit.

But the extra cash hasn't been forthcoming and the Red Devils, along with Chelsea, are monitoring the situation closely.

The Blues were heavily linked with the 28-year-old over the summer.

Antonio Conte was willing to shell out upwards of £35m to secure his signature and had three bumper bids rejected, says the Daily Star.

However, the Italian boss remains a huge fan and has not given up hope of luring him to England in January.
