If you thought Sir Alex Ferguson's days of controversy were over, you were very much mistaken.
In the Manchester United legend's most recent biography 'Leading', the Scotsman revealed his side of the story over what happened with the infamous transfer of Paul Pogba to Juventus.
Sir Alex implied Pogba's agent, Mino Raiola, was to blame for the move, describing his meeting with the Dutchman as a 'fiasco'.

The 13-time Premier League winner wrote: "There are one or two football agents I simply do not like and Mino Raiola, Paul Pogba's agent, is one of them."
However, since Ferguson's quotes have been unearthed and publicised, Raiola has reacted and responded to the Scotsman's criticism.
According to the Daily Mail, he said: "Those words don't describe my work in a negative way. I rate them as a proof that I am good at my job.
"I have to do what's best for my players' sake. If I had looked only at my immediate gain, I would have kept Pogba in Manchester."
Raiola's decision to ship Pogba to Juventus has proven a success, of course, given the Frenchman's rise to one of the world's best central midfielders.
And in quite extraordinary circumstances, Raiola has questioned Ferguson's knowledge of the 22-year-old.
"I put Pogba's interests first and we decided to go to Turin. Maybe Ferguson only likes those who obey him. From his quotes, I understand that Ferguson still doesn't have a clue who Pogba really is.
"Ferguson was an excellent manager, but the greatest managers can be wrong sometimes."
It remains to be seen who exactly is right in this instance, with both seemingly unwilling to back down, though one thing is for sure - Ferguson will be regretting the day he sanctioned the sale of one of Europe's brightest and up-and-coming stars.
