United are increasing their efforts to land Arturo Vidal or Ilkay Gundogan as well as Juan Mata after Michael Carrick's ankle injury.
The impending capture of the Spaniard and the untimely injury to Carrick against Sunderland on Wednesday night have seemingly intensified club officials' attempts to bring in another world-class signing to bolster the engine room and United's chances of a top-four finish.
Juventus do not want to sell Vidal but could be tempted to accept a huge offer for the Chilean midfielder who is understood to be earning less than £100,000-a-week in Turin.
The Serie A champions tied the ex-Bayer Leverkusen star, 26, down to a long-term deal last year and could demand close to £40million for him, knowing that United are desperate to strengthen.
Gundogan, 23, looks less likely at the moment as he is currently out with a back injury and would not be able to fill the immediate void left by Carrick, who is expected to be out for three to four weeks after hurting his ankle.
Borussia Dortmund star Gundogan appears to be more of a summer target as his club are still fighting for the Champions League and, like United, not assured of qualifying for the competition next season.
Other midfield targets that United are looking at include Sporting's William Carvalho, Napoli's Marek Hamsik and Inter's Fredy Guarin while boss David Moyes will watch Borussia Monchengladbach Patrick Hermann on Friday night.
