Neymar chose to quit Barcelona for PSG out of pure ambition.

That's according to French pundit Didier Roustan on Europe 1.

There's claims Neymar is already regretting his world record move just months after leaving Barcelona.

And Rouston said: "Even if his arrival at PSG is partly financial, he could have had the same thing at Barça, but it's mainly that he wants to be number 1 worldwide and staying in Barcelona, he always remained in the shadows from (Lionel) Messi.

"He has been four years in the shadows but here he wants to be the best. These people have an ego, that's normal. There at PSG, he is sure to be the boss which could not be the case in Barça.

"He was exiled on the left, now he plays his own game which is very different."
