Man United sign South American wonderkid, 18, as Ruben Amorim's second summer recruit

Manchester United have confirmed the signing of Paraguayan teenage sensation Diego Leon ahead of next week's pre-season training.

United agreed a deal worth up to £7million to sign the 18-year-old defender from Cerro Porteno, making him the club's second signing of the summer after they brought Matheus Cunha over from Wolves for £62.5m last month.

While Leon is determined to fight for his spot, it is expected that Ruben Amorim and his coaching staff will monitor him in pre-season before deciding whether to include him in the first-team squad or send him out on loan.
