The Argentine midfielder has also attracted interest from Inter Milan and Paris St Germain, but only this week signed a new five year deal with Benfica that will double his annual earnings to £2million.
Despite the new deal, Gaitan still has a release clause of £40million in his contract. Benfica had wanted to increase this but were unable to do so.
Ferguson may see Gaitan is a direct replacement for Paul Scholes and the ideal player to sit behind the forward. According to the Telegraph, he is now getting ready to make a move.
United wanted to make a bid for the Argentinian in the January transfer window, but the new contract may put the transfer on hold until the summer.
