It's pretty safe to say, Sir Alex Ferguson is not a big fan of Mino Raiola.
The Italian-born football agent was blamed as the main factor behind Paul Pogba's departure from Manchester United in 2012 and infamously clashed with Ferguson over the youngster's contract at Old Trafford.
Four years later, and Man United were forced to fork out a record-breaking £89 million to bring Pogba back to the club in what also proved to be a very lucrative deal for Raiola.
Ferguson's legendary status at Old Trafford means many of the club's supporters usually take his word as gospel and therefore Raiola hasn't been a popular figure around Manchester over the last few seasons.
But now the super agent, who also has United's Zlatan Ibrahimovic and Henrikh Mkhitaryan on his books, has opened up on the disagreement with the Red Devils' old manager.
In an interview with the Daily Mail, Raiola defended his decision to take Pogba to Juventus and played down the dispute with Ferguson.
"It was never an issue,’ says Raiola. ‘Moving in 2012 was a necessary step because Paul wouldn’t have progressed the way he did otherwise.
"I had two meetings with Mr Ferguson. The first was nasty on his part but the second, I’d never had so much fun in my life! Mr Ferguson is entitled to his opinion and, though I don’t have to agree with it, I have a great deal of respect for him.
"He is an iconic manager but I still believe the value of Paul today confirms I was right to do what I did. We had different ideas of where Paul was."
Pogba's decision to move to Turin proved highly successful as he won four Serie A titles, two Italian Cups and reached the final of the Champions League in 2015.
But Raiola revealed that Juventus wasn't his preferred destination for the now 23-year-old.
He added: "What people don’t realise is that I did everything to try and persuade Paul not to go to Juventus.
"Serie A clubs were not known for developing young players at the time. The last had been Paolo Maldini at AC Milan in 1985. I didn’t think it was right.
"So three months down the line, he is at Juventus and I said we started a bad relationship here, everything I say you don’t listen to me and Paul just said, 'It’s not that I don’t listen, it is just everything I have done in life, I have done the hard way. I want to do it the hard way.'"
Pogba has come in for some criticism for failing at hit the ground running under Jose Mourinho, however, his agent has backed him to be a success and even joked he deserves a knighthood.
"It’s true Pogba is not playing his best yet, he is taking time to adjust but people don’t always see the bigger picture. He will dominate for 10 years. He is United’s lost son.
"One thing I see though is that Mr Ferguson was made a Sir — maybe I too should be a 'Sir' for bringing Paul back!"
