Rivals Manchester United and City are to lock horns again in the pursuit of young Argentine striker Rogelio Funes Mori.
United have sent scouts to Argentina to watch the 19-year-old among others at River Plate while City have also been swift to register interest.
The Barclays Premier League duo are not alone though as AC Milan, Real Madrid and Barcelona are also monitoring his progress.
Mori actually trained at Chelsea as a 12-year-old but was spotted there by River Plate.
United, meanwhile, have added Roma's Daniele De Rossi to their list of possible midfield transfer targets.
