Two Benfica youngsters will reportedly undergo trials with Manchester United.
It has been claimed that a number of clubs, including Barcelona and Arsenal, have expressed an interest in Joao Filipe and Joao Virginia, both of whom are 15.
However, United have stolen a march on their rivals by reaching an agreement with their Portuguese counterparts to have a closer look at the pair this summer, according to Sky Sports News.
The report adds that, should they impress Louis van Gaal and his coaching team, both are likely to be offered permanent contracts to remain at Old Trafford.
Filipe is a winger who has drawn comparisons with former United talisman Cristiano Ronaldo, while Virginia is a goalkeeper.
