Sporting Lisbon goalkeeper Rui Patricio has emerged as a summer transfer target for Manchester United according to talkSPORT.
The 23-year-old stopper is widely regarded as one of the brightest young prospects in Europe.
The Red Devils have been heavily linked with a move for Atletico Madrid's David De Gea, with a £17.8million fee thought to have already been agreed between the two clubs.
De Gea would move to Old Trafford as a long-term replacement for the retiring Edwin Van der Sar.
But United boss Sir Alex Ferguson has already got a contingency plan in place, in case the prospective deal falls through.
Reds midfielder Luis Nani is alleged to have recommended his Portuguese teammate to Sir Alex, who reportedly sent Manchester United scouts to run the rule over Patricio at the weekend.
Interest in Lisbon's star stopper is thought to be high with a number of clubs across Europe said to be monitoring the player's situation.
If Manchester United wish to step up their pursuit of the promising Portugal international, then they will likely face competition from a number of potential suitors.
A deal to bring Patricio to Old Trafford remains far from concrete, but Manchester United fans will no doubt be anticipating some movement to recruit the goalkeeping position when the transfer window reopens in June.
