Neymar didn't exactly leave Barcelona in the most amicable of fashions this summer.

Although initial rumours of a move to Paris Saint-Germain seemed mere speculation at first, proceedings turned frosty when the Brazilian's intentions became clear.

Appeals from the powers that be at the Nou Camp and even La Liga tried to impede the mammoth £199 million move that was eventually concluded on August 4.

Despite the rough goodbye, however, Neymar decided to visit the Barcelona training ground - Ciutat Esportiva - to see the likes of Lionel Messi and Luis Suarez once again.

According to Sport, those present described the appointment and 'surreal' with the typically relaxed Neymar asking: "Would you take me back?"

It's hard to interpret Barcelona's openness to his visit as incredibly humbling or as some kind of reluctant compromise.

This is the player, after all, who took his anger out on club president - Josep Bartomeu - on social media in September, lamenting: "This president is a joke."

To which the president replied: "He did not act with the right decorum. I do not know [why he left]. You should ask him. He did not tell us.

"For money? To lead a sporting project? Here, he was at the best club in the world surrounded by many of the best players in the world and without a doubt, that is Messi."

More and more information is continuing to emerge about the tempestuous final moments of Neymar's career and it seems comparisons were even being drawn to Ronaldinho.

According to a source close to Neymar, liaising with Goal.com, Barcelona even taunted the 25-year-old with the case study.

They explained: "He does not like any coach.

"Ever since he has been in Santos, he has had problems with all his coaches, whether club or selection. He complained about Luis Enrique methods of work in general, his choices on the regular players and substitutes. 

"The highlight was the blood drive against Unzue, Enrique's assistant, when he told him to be careful not to finish like Ronaldinho and focus more on his football."

Well then.

Juan Carlos Unzue was undoubtedly out of order dropping that comment and about a player treasured by all at the Nou Camp, too. You'd be hard pressed arguing that Ronaldinho left in quite the same fashion.

On the whole, though, the source reiterates Neymar's difficulty with coaches that has followed him to Paris this summer. Unai Emery's job was made so much easier, yet so much harder when Neymar signed.
