Manchester United legend Gary Neville is convinced Luke Shaw will prove money well spent.
Neville is the teenage left-back's coach at England level and saw him at close quarters during England's World Cup preparations and time in Brazil.
"I am trying to keep guarded here about the size of talent that exists in this footballer," he told the Manchester Evening News.
"You are talking about real brilliant potential. The reason United spent £27m on a left-back at his age is because they see the huge talent and I can only endorse that talent.
"You have to watch him at close hand to realise that this is an incredible and hugely talented football player. Luke Shaw is fantastic."
