Manchester United are reportedly interested in bringing Olimpia Asuncion teenager Blas Miguel Riveros to the Premier League at the end of the season.
The 18-year-old recently received his first call-up to the Paraguay national team and it is understood that his development over the last few months has drawn the interest of a number of European clubs.
According to O Jogo, Man United currently lead the race for the teenager, but Barcelona and Benfica are also closely monitoring developments with a view to a move this summer.
It is understood that Paraguayan side Olimpia would accept offers in the region of £1m for the left-sided player.
