Roy Keane: 'Manchester United need six top quality players'

Manchester United legend Roy Keane believes that the side need as many as half-a-dozen "top quality" signings this summer.

United's Champions League hopes are hanging by a thread after suffering a 2-0 reverse away to Olympiacos on Tuesday evening, and former captain Keane admits that there must be a huge overhaul in the close season.

He told ITV Sport: "I think United need six top quality players. I would think David Moyes has been shocked. I think when he went into United in the summer he probably looked at the players and was expecting great things.

"Privately, he's probably been shocked at the lack of quality he's working with.

"There's some players playing tonight for Man United who just aren't showing enough quality."

United are currently sixth in the Premier League, 15 points behind leaders Chelsea.
