Neymar quits Barcelona training after bust-up in Miami, cancels China event over 'transfer business'

It was reported last week that the Brazil captain had agreed terms with PSG on a world-record £195m move to the Qatar-backed Ligue 1 giants, and the on-field joust with new signing Semedo will do little to dispel rumours about the player's happiness.

The Daily Mail have obtained footage of the incident from a training session in Miami as Neymar and former Benfica player Semedo clash before the players have to be dragged apart.

Javier Mascherano appears to intervene before Neymar appears to be restrained by Sergio Busquets.

The incident ends with Neymar walking away after tearing off his bib.

New Barcelona coach Ernesto Valverde looks on as Neymar wanders away clearly still unhappy with the events. Neymar then heads for a car park after crashing a football off a training goal before departing the scene.

Suggestions that the Brazilian might have weighty matters on his mind increased when Chinese travel agent Ctrip posted on its official Weibo account that it has had to cancel an event with Neymar because he is "busy with transfer business".

Ctrip said the event was scheduled for Shanghai next Monday and that anyone who had bought tickets would be refunded.

Barcelona president Josep Bartomeu has stressed that Neymar is not for sale.

In an interview Bartomeu insisted: "He is not on the market...He is part of this trident."
