Former Manchester United assistant manager Rene Meulensteen says harmony was the key to the club's success under Sir Alex Ferguson.

Meulensteen was his tactical guru, putting on training sessions that had to test the likes of Ryan Giggs, Paul Scholes and Cristiano Ronaldo on a daily basis.

He recalled to the Manchester Evening News: "There was no jealousy or egos. It's hard to replicate that in football.

"I remember having a cup of tea with the manager not long after he retired and I said 'there was not one single day that I travelled to Carrington and felt under stress, or anxious about something'. That says a lot about the way Sir Alex Ferguson man managed the situation and all the people. Because we know about the demands at Man United, which is to win, win win. And there could be plenty of stress, but he managed that so well and that was unique.

"When everyone pulls in the same direction, it's quite easy. We expected those players to be world class performers every single game they played and they expected world class support, with the training sessions we put on, the recovery, the medical department and everything.

"It was just an absolute delight to work with so many motivated and highly-talented players."
