Manchester United are said to have sent scouts to Portugal on Saturday to watch a transfer target.
The Red Devils, per The Mail, have very keen interest in 17-year-old Porto winger Goncalo Sousa.
The winger was making his first team debut, as he came on in the 83th minute of the win against Chaves.
Sousa may not be ready for the Premier League as yet, but United want to steal a march on other teams.
He shone recently in the UEFA Youth League, while he is expected to get a lot more game time at senior level next season.
Whether he is one United sign for the present or loan him out after securing his signature is not yet clear.
