Former Manchester United captain Nemanja Vidic believes his old club miss the expertise of Carlos Queiroz. Queiroz, Sir Alex Ferguson's right hand man, worked tirelessly with the United back five which was rock solid in the 2007-08 season when they won the Premier League and Champions League double.
And Vidic, looking back on his Old Trafford career after joining Inter Milan, doesn't believe there will ever be a stronger defensive unit under new boss Louis van Gaal.
"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.
"But working with Carlos at that time was a big influence on us and that team. Plus, you had to look at the manager too. Sir Alex Ferguson picked the right players in the right positions.
"He had brilliant players in that squad and he got the positions right and that set up the balance of the team. But there were a lot of things which were decisive in that season which all contributed to us doing well.
"The key to that season was the consistency over a number of games throughout the whole season. It was the players, the coaches, the manager.
"The balance of the defence and how we played as a unit over the entire season which brought it all together."
