Despite being linked with a host of big names for 1 1/2 transfer windows now, United manager David Moyes and CEO Ed Woodward have been able to sign only one player Marouane Fellaini.
So it appears that Moyes has turned to his predecessor for help and Fergie called former United centre half, and current PSG boss Laurent Blanc about striker Edinson Cavani recently.
Apparently Blanc told his former boss that while PSG would not listen to bids in the January transfer window for Cavani, they would be willing to discuss the possibility of a sale at the end of the season.
Cavani joined PSG for a reported €64m from Napoli in the summer and has been a success in Ligue 1, scoring 17 goals in all competitions this season. But Cavani is said to be unimpressed with the standard in Lique 1 and the lack of passion and atmosphere in the grounds and would be open to a move in the summer after the World Cup.
If United was able to sign Cavani, the immediate thought would be that they will sell Wayne Rooney, who will have only one year left on his current deal next summer. But would they instead let Rooney run down his contract hoping that they can still sign him to a new deal and instead let van Persie go as Cavani would appear to be a more logical replacement for the Dutch striker than for Rooney?
