Former Manchester United defender says that the club is unrecognisable under Louis van Gaal.
Speaking to the Guardian, Ferdinand says that supporters used to watching free-flowing football will be left disappointed.
“I was talking to Nemanja Vidic on the phone and we were both saying that the change is unreal in terms of the personnel and the transfer policy.
“It doesn’t look like anything I knew from when I was there. Even the sponsor that was there for so many years has gone, with Nike being replaced by Adidas. Everything has changed, other than the groundsman and the chef.
“Man United supporters have to go away and re-educate themselves on how to watch Man United.Don’t go there expecting to see free-flowing, attacking, gung-ho football.
“If you’re losing 1-0 in the 89th minute, don’t expect that free-flow … get the ball wide, cross it or get the ball into the strikers. The only thing I can see that is similar sometimes is, if they win the ball high, they do like to go straight for you.”
Ferdinand also believes that he never got enough credit from Alex Ferguson, although that drove him on to succeed.
Following the arrival of Vidic from Spartak Moscow in 2006, the duo formed the bedrock upon which Manchester United won five Premier League titles as well as the Champions League.
However the pair felt they were never praised enough, although Ferguson has since explained his reluctance.
“It is one of the things that pushed me on. With Ferguson, he was very much on your case at all times,” said Ferdinand, who left the Red Devils to join QPR in 2014 before retiring in the summer.
“It was good. He was very much about personalities and working you out. I used to feel I was never given enough credit. Me and Vidic used to talk about it quite a lot.
“It wasn’t until I retired he said ‘your personality, if I had given you too much credit, you might have got carried away’. All the time I was trying to get that credibility from him. He did have that for me as a player.”
Serbian Vidic left Old Trafford at the same time as Ferdinand, but has struggled at Inter Milan and is yet to play this season.
Ferdinand also spoke of his disappointment at never having been given the United captaincy on a permanent basis. When asked if the snub had upset it, the former centre-back told CNBC: “I would be lying (if I said) it didn’t.
“It is one of the things that pushed me on.”
Ferdinand then refused to rule out a move into management.
“It’s where I am most comfortable now,” he said of his role with BT Sport. “I really enjoy it.
“It’s a great learning curve. I am watching football on a regular basis – that will put me in good stead for if and when I do go into any type of management.”
