Manchester United remain interested in Watford defender Pervis Estupinan.

The Daily Express says, however, Ole Gunnar Solskjaer's side face competition from Barcelona, Atletico Madrid and Tottenham for his signature.

Estupinan arrived at Vicarage Road in July 2016 but has never made a senior appearance for the Premier League outfit.

The once-capped Ecuadorian international has subsequently spent loan spells with Spanish quartet Granada, Almeria, Mallorca and most recently Osasuna.

The 22-year-old has made 30 appearances in all competitions for the 11th-placed La Liga club, scoring once against Valencia and providing a further five assists.

His displays have seen him linked to various clubs including the Red Devils, with Old Trafford legend Antonio Valencia endorsing his compatriot back in April.
