Amad Diallo's former youth coach Denis Cerlini says Manchester United's new signing is a special talent, but former Italian goalkeeper Giovanni Galli has warned he's going to need to get stronger in order to survive in the Premier League.
Diallo only made five senior appearances for Atalanta, but it was enough for United to splash out £37million, including bonuses, on the 18-year-old winger.
And Cerlini, who coached Diallo at amateur side Boca Barco, is confident he has the talent to prosper in the Premier League.
'From the very first moment, it was evident the kid was special,' Cerlini told BBC Sport.
