Man Utd have upped their interest in Benfica's Joao Felix, after sending scouts to watch him in Portugal for fresh checks on the teenage sensation.
The 19-year-old scored in a 4-1 win for his side over Santa Clara in Lisbon on Saturday, to help them seal the Primeira Liga title.
As reported by the Star , United scouts were on hand to cast a watchful eye over Felix, who has attracted plenty of interest across Europe.
Real Madrid , Barcelona and Man City are all said to been keen on the youngster, whilst Juventus have already had a £75m bid rejected.
Representatives of Atletico Madrid were also in attendance at the fixture, as they look to replace the outgoing Antoine Griezmann.

Benfica are resigned to losing their teenage prodigy, but will not accept less than £100 million.
That is not thought to have put off United, with Ole Gunnar Solskjaer keen to invest in youth as he plans a summer rebuild of his squad.
Felix has made waves in Europe this season, scoring 20 goals and making 11 assists in his debut campaign.
The attacking midfielder has rose through the ranks at his current club, and could now be on course to make his full international debut, having represented Portugal at under-18, under-19 and under-21 level.

A number of other clubs were at the clash, including Everton and Bayer Leverkusen, but were watching different targets.
Solskjaer's strategy to invest in youth could also see the Red Devils land promising Ajax defender Matthias de Ligt.
The Dutchman is reportedly open to a move to Old Trafford as they look to shore up their problem defence.

Barcelona lead the race for his signature, but there are question marks over whether they can afford both de Ligt and the aforementioned Griezmann, who is set to join them this summer.
The Spanish club already have de Ligt's Ajax teammate Frenkie de Jong on the way for £75 million, and may have to offload some players if they are to fund a move for the 19-year-old.
That could leave the door open for United to swoop, with de Ligt not thought to be put off by playing Europa League football next season.
