According to new transfer reports, both Manchester United and Real Madrid have agreed to a £25 million transfer fee that will see Serbian defender Nemanja Vidic swap the red of Old Trafford for the white of the Santiago Bernabeu.

United boss Sir Alex Ferguson is believed to be very pleased with how youngsters Chris Smalling and Phil Jones have performed so far this season and may see this as the right time to let Vidic, 30, go.

Earlier, a week after United were mauled 6-1, at home, by local rivals Manchester City, it was rumored that Real had placed a £10 million offer for the defender.

These reports aside, however, there are questions being asked of the apparent ease with which Ferguson has agreed to the sale of one of his more important players. One possibility, according to a Footy Latest report, could be that Vidic may only have a few years of top-class football left to give and the United boss would, therefore, rather spend a few years now grooming the younger pair of Smalling and Jones for future campaigns.

Nemanja Vidic joined Manchester United from Spartak Moscow in 2006, for a fee of around £7 million. He has made 164 appearances for the Red Devils and scored 14 goals. He has also made 56 international appearances for Serbia.
