Manchester United and Manchester City are among the teams chasing after River Plate prospect Enzo Fernandez.
The 21-year-old midfielder has emerged as a target for many top European teams.
With United losing several midfielders, they are eager to add quality to that part of their team.
City are also on the hunt for a new midfielder, as Ilkay Gundogan is leaving at the end of the season.
South American outlet Clarin claims United are willing to pay the player's release clause of €20 million.
City are also willing to do so, and they have already signed Julian Alvarez from River Plate in recent months.
