Arsene Wenger has told Granit Xhaka he has to learn from his mistake after the Arsenal summer signing left the Gunners with 10-men during the 3-2 win over Swansea on Saturday (15 October).
The French boss believes that the red card was "harsh" but admitted he will need to speak with the midfielder as the Gunners suffered a lot to secure all the three points.
Arsenal looked in line to get a comfortable win over the Wales side after Theo Walcott scored two early goals. However, Gylfi Sigurdsson capitalised on a Granit Xhaka error to reduce the gap and give Swansea some hope before the break.
Mesut Özil restored the two-goal difference for Arsenal but substitute Borja Baston handed the visitors a new lifeline to set up a tense final. Yet, Xhaka put the victory under further scrutiny after seen a seen a straight red card for a cynical challenge on Modou Barrow with 20 minutes to play.

Wenger believes that referee Jon Moss should have sawn only a yellow card but still believes that the Arsenal summer signing will have to learn to avoid rash challenges ahead of the future.
"It looked harsh to me. But it was a deliberate foul. It looked a dark yellow – and the referee went for a bright red," Wenger said. "I think intelligence means you don't make the same mistake twice, and I hope he learns from that.
"Before, in Germany, he had some [red cards] but I don't think he's a dirty player at all. Sometimes there have been some clumsy tackles because he's not a natural defender, he's a guy who likes to play forward. I will speak to him. I think Barrow made a lot of it as well, because he could go on. But the referee saw a bad tackle and you have to respect that. It is what it is, and he has to learn from it."
Petr Čech managed to secure the three points for Arsenal at the end with a string of late saves. Yet, Wenger was not completely happy as believes that the Gunners should have killed the game before.
"Yes, what looked to become a comfortable afternoon finished in a very uncomfortable way. But we just got over the line," the boss added. "I thought we played some fantastic football in patches but at 2-0 maybe we lost our focus a bit. After that, at 3-1, [it happened] again.
"When we were down to 10 men at 3-2, we could have scored the fourth goal but we could have conceded as well. In the end, we just got over the line. We played together, with spirit until the end. It was difficult at the end."
