There was talk of division in the Arsenal ranks when Alexis Sanchez scored for Arsenal against Crystal Palace in December, when many of his team-mates turned their backs on him.
But Hector Bellerin has spoken about the incident and insists there was no deliberate show of disunity.
He did, however, admit that Sanchez, who has since moved to Manchester United, could demand too much from team-mates.
'There was one game against Crystal Palace,' Bellerin told the Oxford Union.
'We celebrated a goal and some of the players went I stayed back, I was talking to Calum Chambers and others because there was some tactical stuff.
One suggested theory had been that the Arsenal players made a show of refusing to join Sanchez after the goal as they were unhappy with his desire to leave the club.
Arsenal legend Thierry Henry said he thought the celebrations indicated 'division in the team'.
Bellerin moved to smooth over the situation by explaining it was for tactical reasons but did admit that occasionally Sanchez would ask too much from those around him.
'(Sanchez is) one of the best in the Premier League for sure but he is a player who always wants to win,' said Bellerin.
'He demands from everyone, sometimes it can be too much. The great thing is he wants to win, to give 100 per cent,' he added.
