Arsenal head coach Unai Emery insisted his side do not have disciplinary problems after Sokratis Papastathopoulos became the latest player to see red for the Gunners.
“I think we changed more than we want, but a red card can come,” Emery said. “Two yellow cards and it’s the referee’s decision.
“After, I think we must learn to play – when it’s coming like today – with one less player on the pitch. It was not a good experience today, because we couldn’t do our work in difficult moments, in difficult minutes, with one less player, like we wanted.
“I think we can do better. I am positive in the first 40 minutes because I think, with respect to them, we imposed our gameplay in these moments.”
