Manchester United have completed the signing of Aliou Badara Traore from Paris Saint-Germain.

The 16-year-old is regarded as one of the brightest prospects in French football and was also scouted extensively by Manchester City and Juventus.

The midfielder travelled with United’s Under-18s squad for their pre-season tour of Austria but only made his debut in the 3-2 defeat to Wolves in the Premier League Cup on Saturday.

‘Traore is a boy we’ve been looking at for a while,’ United’s Under-18s coach Kieran McKenna told MUTV.

‘He is a really powerful midfielder who likes to run box to box. He is very strong technically and is improving all the time.

‘He’s a nice man and his English is improving.

‘He’s settling in well with the boys and has taken to the club really well.’
