Hereisthecity - Former Manchester United defender Nemanja Vidic believes the Red Devils are missing former coach Carlos Queiroz with the current side proving shaky at the back.

Nemanja Vidic, who spent eight years at Old Trafford, before joining Inter Milan at the end of his contract in the summer, feels that the club are missing some of Queiroz’s input, especially in a defensive capacity.

Queiroz was assistant to the legendary Sir Alex Ferguson at Manchester United during the 2007-08 season, a campaign in which the club won the Premier League and Champions League double.

Vidic was part of this success, alongside Wes Brown, Rio Ferdinand and Patrice Evra, all of whom starred in Sir Alex's defence. The ex-United defender believes that this back-four had the perfect balance; something that current United manager Louis van Gaal is yet to achieve.

“The defence that year was Wes Brown, Rio Ferdinand, myself and Patrice Evra and we had great balance,” said the Serbian.

“We worked a lot in training on this defensive shape with Carlos Queiroz. Patrice was the one who was going forward on that left side, almost as a winger."

“Then you had Rio and I in the middle with Wes on the right. He was a natural defender who could get forward as well but with Patrice attacking it gave us the right balance for Wes to stay more in position to stop counter attacks."

“We had a really great balance and we had Edwin van der Sar behind us. He had great experience and was talking to us all the time. He could pass the ball, too."

“He was a great passer, like an outfield player. It was like having a midfielder and goalkeeper behind you. He could pick out passes and you always felt confident giving him the ball."
