UNITED and City are on collision course in a mega-bucks battle for fast rising Cameroon star Stephane Mbia.
The 21-year-old Rennes defensive midfielder, who can also play at right back, is attracting interest across Europe.
But the player, whose value could reach Â£10m, says that both Manchester clubs have already been in contact.
Mbia has two years left on his contract at the French club but will consider his future at the Stade de la Route de Lorient at the end of the season.
"I'll think at the end of the year if the big offers I'm receiving are still up to date," he said.
"I've had contact from teams in England and Italy. There are contacts with Manchester United, Manchester City, Liverpool and in Spain there is Barcelona as well.
"For the moment I'm not thinking of it and I will stay with Rennes. I'll rely on people like general manager Pierre Dreossi, who knows me and my parents very well. Then it'll be me who takes a decision."
Mbia would fit the bill for both Reds boss Sir Alex Ferguson as he mulls over business in the summer.
Ferguson is always seeking to add more youth to United's senior squad and Mbia fits the profile of a young, mobile, athletic and powerful player.
The Red Devils are well equipped in midfield at present but Paul Scholes is now 33 and the six foot-plus Mbia has the added attraction of being a capable right- back. United are looking to bring a defender in as insurance with Gary Neville only just on the brink of a senior return after 12 months out and Wes Brown's Old Trafford contract saga very much unresolved.
