Manchester United are rivaling Chelsea for Roma midfielder Radja Nainggolan.
Sky Sports says United have serious interest in the Belgian international as they battle Chelsea for his signature.
The Blues failed in a £34million bid to bring him to Stamford Bridge last summer, and now risk losing out to him to Jose Mourinho.
The United manager needs to find a new midfield addition having sold Morgan Schneiderlin to Everton and with doubts persisting over Marouane Fellaini's future.
For his part, Nainggolan has stated he's happy with life in Rome.
