Neymar showed that Barcelona remains in his heart when he shared a photo of himself watching the Blaugrana’s 3-0 win over Girona with his son last month.

The Brazilian enjoyed four successful seasons at the Camp Nou before completing a £197 million move to Paris Saint-Germain in the summer.

Yet for all that he had done for Barcelona, the Spanish giants were unwilling to make Neymar’s departure a smooth one.

Barcelona announced in August that they would sue the 25-year-old for £7.8m for allegedly breaching his contract.

The Catalans also demanded Neymar return the loyalty payment he received after he renewed his contract at the Camp Nou in October 2016.

The dispute prompted Neymar to hit out at Barcelona’s board.

“I don't have anything to say to the Barcelona board,” he said, per the Telegraph.

"Well, actually I have something to say: That I am disappointed with them.

"I spent four years there and was very happy. I began happy, spent four years happy and left happy. But not with them. 

"For me, they shouldn't be in charge of Barca. Barca deserve much better, and everyone knows this."

Neymar's move to PSG was messy

Yet while Barcelona were demanding money from Neymar, the forward’s father was demanding money from Barca.

Neymar Sr. expected a €26 million loyalty payment which Barcelona refused to pay.

Messy stuff, right?

Neymar even made a demand to UEFA

The refusal to pay the €26m bonus was the final straw for Neymar’s lawyers, who, according to Spanish outlet AS, decided to take the legal wrangling to new lows.

They claim that Neymar’s lawyers were so infuriated with Barcelona’s behaviour that they advised the player to ask UEFA to dispel the Blaugrana from the Champions League.

Now, Neymar has a lot of influence after becoming the world’s most expensive player but that seems a rather dramatic request.

Needless to say UEFA didn’t even bother to consider it.

And it would have been a real shame if they had, for there’s every chance we’ll see PSG against Barcelona in the latter stages of this season’s competition.

The two clubs played out a tremendous round-of-16 tie last season in which Barcelona recovered from a 4-0 first leg deficit to win 6-5 on aggregate, with Neymar single-handedly inspiring the Spanish club to victory.

Now that the Brazil star has switched allegiances, who wouldn’t want to see Neymar against Lionel Messi and co.?
