If this is true, we need to be all over this one. It looks like Diego Costo to Chelsea is happening, so they'll definitely need a striker, so a swap deal could be on the cards. It seems Mourinho doesn't rate Lukaku that much. Loaning him out and always moaning about lack of strikers.
I'd be happy to see us spend big money on this guy if we can get him. Chelsea sold Mata to Utd, so it is possible that they sell him to another English team.
It could also be his agent fishing for a new deal and reassurances from the manager.
