The People says United boss Sir Alex Ferguson is poised to step in after Barcaâ€™s bid of Â£22million plus Bojan Krkic, 20, was scuppered when their young attacker snubbed the move to Italy.
Udinese want Â£30m but may take less in straight cash. The Red Devils are in the market at Â£25m and possibly could go higher as the two giants slug it out for the 22-year-old.
Barca want to trade players first before committing a huge chunk of their cash to the Sanchez move, despite agreeing a Â£60,000-a-week contract with the player.
Manchester City also fancy the wideman but he is not keen on an Eastlands switch.
