Angel Di Maria was one of the standout performers in Paris Saint-Germain's 2-0 win against Manchester United last week. 

The French side were expecting a tough test at Old Trafford in the first leg of their Champions League last-16 tie but came through unscathed. 

Goals from Presnel Kimpembe and Kylian Mbappe gave PSG a commanding lead to take into the return fixture at the Parc des Princes in March. 

Although he didn't get on the scoresheet, Di Maria provided both assists and ensured he had the last laugh after taking a lot of abuse throughout the match. 

It was the first time the Argentine had returned to Manchester since his departure after the terrible season he spent with United in 2014/15. 

Unsurprisingly, the home fans weren't best pleased to see him as many believe he was nothing more than a passenger during his year at Old Trafford before forcing that move away. 

CONTROVERSIAL MOVE

The details surrounding Di Maria's exit are well documented - in July 2015, he failed to board a flight with the rest of the team for the pre-season tour of the United States. 

Louis van Gaal, who was United's manager at the time, admitted he 'did not know why' the forward wasn't on the flight and less than a week later, his transfer to Paris was confirmed.

The reasons why Di Maria decided to jump ship were not ever fully explained, but after a triumphant return to the Theatre of Dreams last week, he's finally revealed why he left so soon. 

According to the player himself, it was an argument with Van Gaal after just two months that caused a rift between the pair and changed everything for him in England.  

THE BUST UP THAT CHANGED EVERYTHING

"I was at Manchester and everything was fine with Van Gaal during the first two months," Di Maria told Argentine TV programme ESPN Redes, per the Mirror.

"After one fight, things weren’t the same. The relationship wasn’t the same.

"The fight with Van Gaal occurred because he was always showing me bad and negative things and all that held me back.

"One day I fought with him. I told him I didn’t want to see those things anymore, that I was doing things well and asked him why he wasn’t showing me good things.

"He did not like how I spoke to him and from there the whole problem started."

NOT BACKING DOWN

So, it appears that Di Maria has put the blame on Van Gaal for his troubles at Man United.

No player enjoys being criticised by their manager, but the feud that developed between the pair seems very extreme. 

Clearly, though, the 31-year-old has a much better relationship with his boss these days and he's shining under Thomas Tuchel at PSG this season.
