The Russians want to follow their £20m capture of Inter striker Samuel Eto'o by adding a top-class defender.
And United skipper Vidic, 29, is at No 1 on their wanted list — with a top Russian source telling SunSport that a bid for the Serbian is "imminent".
The news will have United boss Alex Ferguson sweating, especially with just two days left of the transfer window.
Fergie may have a glut of centre-backs but will not want to lose his leader, who cost £7m from Spartak Moscow in January 2006, at any price.
That will not stop Anzhi testing United's resolve — especially as money is no object for the Manchester City of Russia's top flight.
Anzhi are controlled by Russian billionaire Suleyman Kerimou, who has an estimated personal fortune of £5bn.
He stunned the football world last week with his swoop for Eto'o, who is said to be on a whopping £300,000 a week.
cannot sell lar. esp when he is 29 and is able to play till he is 33, so another 4 more years. but if bid for vidic for 50m, then can consider.
i wouldn't buy any player at 29....................
