Manchester United reportedly sent scouts to watch Benfica forward Joao Felix in action against Maritimo, where he scored a brace in his team's 6-0 win.

The 19-year-old is widely regarded as one of the best youngsters in European football and has been linked with the likes of Real Madrid, Juventus, Liverpool and Manchester City in recent months.

United are also said to have a long-standing interest, though, and according to the Daily Mail, the Red Devils watched Felix net twice against Maritimo to make it 18 goals for the season.

Felix - yet to make his senior debut for Portugal - came through the youth system at Benfica and only made his first-team debut for the Portuguese giants at the start of the 2018-19 campaign.

The Eagles are said to be unwilling to sell the teenager this summer unless his £104m release clause is met.
