Manchester United are pushing to beat Brighton to the signing of Valentin Barco.
The 19-year-old left-back has been outstanding at Boca Juniors over the past 12 months.
The Argentine has a £8 million release clause that has alerted a lot of clubs to his situation.
Per The Mail, United, Brighton, and RB Leipzig are the three teams with the most advanced interest.
Manchester City are also monitoring his progress, but may have more intricate plans.
The Citizens would likely buy Barco through another City Football Group club to develop his talent.
