English Premier League side West Ham are tracking Ghanaian midfielder Bernard Mensah.
The 20-year-old midfielder is currently at Portuguese club Vitoria De Guimaraes who have also had interest from Juventus in a part-ownership deal.
West Ham scouts have been looking at Mensah in the past couple of months and may make a move in the summer.
Mensah has played 20 games in the Primeira Liga so far this season, finding the net on four different occasions, including a striker against Porto in September.
He signed a deal with Vitoria until 2018 following an impressive season with the club's 'B' team last season, which saw him promoted to the senior ranks.
