Arsenal manager Arsene Wenger has criticised Emmanuel Eboue for his sending off in the north London derby against Tottenham on Sunday.
Eboue, 25, was dismissed for two yellow cards in the first half and Wenger says he must learn to keep his cool.
“He didn’t sense how far you can go,” said Wenger. “When he got the first card it was unfortunate, but the second one, you cannot complain about that.”
Referee Mike Dean showed Eboue a second yellow after he kicked Luka Modric.
The dismissal meant Arsenal had to play for just under an hour with 10 men at White Hart Lane, though they defended manfully to earn a 0-0 draw.
Wenger added: “During the game he had problems in dealing with his frustrations. We want to play a part in helping him to deal with that.
“The other players want to help their partners to deal with frustrations, but you are also responsible for the way in which you deal with it.”
Eboue has had a troubled season, struggling for form and even being booed by his own fans when he came off the bench but was then substituted in Arsenal’s 1-0 win over Wigan on 6 December.
He is suspended for the Gunners’ FA Cup fourth round replay at home to Cardiff on Monday.
