Manchester United have only one world-class player, according to Harry Redknapp.

The former Tottenham and Southampton manager is unimpressed by the squad that has been assembled by Louis van Gaal at the cost of around £250million.

He believes Jose Mourinho, who is set to be installed as the new United manager in the summer, has a huge rebuilding job at Old Trafford.

Redknapp believes the squad pales into comparison to that at rivals Manchester City and regards David de Gea as the only truly outstanding player at the club.

Writing in the Telegraph, Redknapp said: “Mourinho will need to tear it up and start again because there is no evidence of a team there any more.

“They are miles away from Manchester City, who have five or six fantastic players, and will probably add another three or four more when Pep Guardiola comes in over the summer.

“Where do United go with that team now? All that money spent on average players. Memphis Depay thinks he’s way better than he is, so they tell me, and Anthony Martial has been no world-beater either.

“Apart from the goalkeeper, I can’t see any world-class players and if David de Gea decides to up sticks this summer then they will be in a right mess.”

De Gea is set to be absent on Monday night when United travel to League One side Shrewsbury for their FA Cup fifth round tie.

The latest Manchester United news is that De Gea is unlikely to have recovered from a knee injury, which means Sergio Romero should continue in goal.
