Manchester United have reportedly placed emphasis on signing Sporting Lisbon left-back Nuno Mendes in the summer transfer window.

Still only 17 years of age, Mendes has been touted as one of the best prospects in Europe, although he has yet to make a senior appearance.

Mendes shares an agent with Man United star Bruno Fernandes and, the Portuguese outlet Record claims that the Red Devils are hoping to use their connections to land the Portuguese teenager.

The report adds that the 20-time English champions previously tried to sign Mendes in January, but were unable to get a deal over the line.

Meanwhile, a number of other clubs across Europe are believed to have since joined the race for Mendes’s signature.
