Emirates pair had dressing room altercation following needless booking.
Arsenal duo Robin van Persie and Abou Diaby were involved in half-time altercation during the 3-1 win over Blackpool last Sunday.
The Dutch international was furious when Diaby picked up a needless booking after kicking the ball away in anger at referee’s Lee Mason decision.
Van Persie allegedly told the French midfielder he was an idiot and he was selfish for picking up the booking.
The Gunner’s striker is better placed than most to make the judgement after he himself was booked, and then sent off, for kicking the ball away against Barcelona.
Diaby also has history of letting his emotions get the better of him as his red card against Newcastle United proved.
He fell for the winding up tactics of Joey Barton, and allowed the Magpies to stage a remarkable comeback from four goals down to draw 4-4.
Van Persie felt his it was his job as vice-captain to say something to the midfielder in much the same way Tony Adams would have done.
He wanted to remind Diaby of his collective responsibility, as the incident could have taken the gloss off the Frenchman’s game after scoring the opener in the win at Bloomfield Road.
