Jose Mourinho's tenure at Manchester United ended in December after a number of very poor performances in the first half of the season.
A 3-1 defeat at the hands of Liverpool was the final straw and 'The Special One' was sacked ahead of a busy period of festive football.
It was Ole Gunnar Solskjaer who replaced Mourinho at the helm, and since taking over, the club legend has overseen an impressive seven wins from seven games.
He appears to have brought United's mojo back - the team are now playing free-flowing attacking football, and the players seem much more happy on the pitch.
In the wake of Mourinho's sacking and Solskjaer's resurgence, Gary Neville has been heavily critical of what Jose attempted to do during his time at Old Trafford.
He claimed that the Portuguese boss tried to "shape his own philosophy" and change the image of the club, by changing the attacking style of play that Man United have become well known for.
Neville went on to say that the owners should learn from their mistakes and never hire a manager that wants to do what Mourinho did again.
They were pretty strong words from the former defender, but it's clear how much he loves the club and wants to see it return to the top.
His comments caught a lot of attention from football fans - and even Mourinho himself - who has since responded to Neville's claims.
JOSE HITS BACK
"He doesn't know my philosophy," Mourinho said during an appearance as a pundit on beIN Sports, per the Mirror.
"I would love to go to a club and to be in conditions to do what Jurgen [Klopp] and Pep [Guardiola] did.
"You look at the team Liverpool started with today, how many players were there before Jurgen arrived? A couple.
"When Jurgen is in the club and wins absolutely nothing for three years he still has the trust and still has the confidence and he still has the conditions to try to keep going and going.
"In my next job, I will not be starting a conversation with a club without knowing exactly what the club wants and what the club has to give in terms of structure and objectives."
So, as well as hitting back at Neville and claiming he doesn't know his philosophy, Mourinho also appeared to take a dig at United for not backing him the way Klopp and Guardiola have been.
And now that he's out of the managerial hotseat, this probably won't be the last time he hits back at one of his many critics.
