Barcelona forward Neymar was embroiled in an fierce row with a Manchester City fan after his side's 2-1 victory at the Etihad Stadium last night.
The Catalan outfit took a decisive lead in the first leg of their Champions League tie thanks to two goals from Luis Suarez, but the win was marred by the incident involving the Brazilian after he was substituted with ten minutes of the game remaining.
The 23-year-old was videoed remonstrating angrily with a fan as he made his way towards the Barcelona bench, with stewards stepping in to separate the pair after a short exchange. The Daily Mail report that the pair resumed hostilities after the final whistles.
The forward told Brazilian media afterwards: "I was just playing with him. He began to curse me and I ended up mocking him.'
'What he told me? I can not repeat it, no,' he added. 'My mother gave me an education. What his mother did not tell him, my mother taught me.'

Neymar could face sanctions from UEFA if Manchester City decide to report the incident, which was not seen by match officials.
Neymar had a quiet night at the office having failed to make an impact in the game. Instead it was down to Suarez to do the damage, with the former Liverpool striker bagging a first-half brace to help Barcelona put one foot in the final eight.
Sergio Aguero pulled one back for Manchester City but Gael Clichy's second yellow put the home side on the back foot before Lionel Messi inexplicably spurned the chance to put the tie to bed from the penalty spot with just seconds remaining.
Luckily enough for everyone concerned the clash between Neymar and the Manchester City fan looked innocuous enough. There's an argument to be made that the players are kept too separate from supporters these days and it's a shame when a referee decides to book a player for sharing his goal celebration with those who support the team.
Indeed you only have to watch the video of Stuttgart's 18-year-old defender Timo Baumgartl being consoled by a fan to realise that it's time for the barriers to be lowered.
