Former Tottenham boss Harry Redknapp has warned Manchester United about their summer transfer policy.

United manager Ole Gunnar Solskjaer is understood to be prioritising promising, British players in his rebuild of the first-team squad at Old Trafford after United missed out on a Champions League berth last season.

Daniel James, the Swansea winger, is closing in on a move to United while there is also interest in Sean Longstaff, of Newcastle, and the Leicester City midfielder James Maddison.

But Redknapp told the Manchester Evening News: "You can only put young players in if they're good enough.

"You can't just go and suddenly say 'I'll put young players in'.

"If they're not good enough, the supporters at Man United aren't suddenly going to say 'well it doesn't matter if we're finishing halfway up the league, we're playing all these youngsters.'

"That doesn't happen. Football fans have got no patience. They're not going to sit back."

He added: "If they're not good enough you can't play them. If they're good enough, great. Stick them in.

"If you find five or six kids like they had with Beckham's group, great play them. I did it at West Ham. I had six kids all come through with [Michael] Carrick, [Jermaine] Defoe, [Rio] Ferdinand and [Frank] Lampard. But they've got to be good enough otherwise you can't play them."
