Arsene Wenger says Arsenal will not be appealing against Granit Xhaka's red card in their 3-2 victory over Swansea.
The 24-year-old was dismissed after 70 minutes for a challenge on Modou Barrow but despite classing the decision as "a little harsh", Wenger will not be challenging the decision made by referee Jon Moss.
Wenger said: "No [we will not appeal the decision]. It looked harsh to me but it was a deliberate foul.
"It looked a 'dark yellow' but the referee went for bright red."
The Gunners made it six Premier League wins in a row, with a brace from Theo Walcott and a goal from Mesut Ozil proving enough though Swansea twice pulled within one, through Gylfi Sigurdsson in the first half and Borja Baston in the second.
Walcott's brace on Saturday made it six goals in five games for the 27-year-old and Wenger believes he is looking much more resilient as a player this season.
"He could have had a hat-trick, maybe even four," Wenger said.
Swansea manager Bob Bradley believes there are a lot of positives his side can take from their defeat.
The American boss was announced to replace Francesco Guidolin on October 3 and has had to wait until after the international break for his first game in the Premier League.
The Swans have now lost their last four league games in a row but Bradley was happy with large parts of their game against the Gunners.
