Their domination continued into the second half as Leandro Trossard made it 3-0 with a swift counter attack. Gabriel Martinelli then rounded off the scoring with an injury time brace.
Prior to that late double from Martinelli both Rice and Gabriel were replaced by Jorginho and Jakub Kiwior respectively. Both appeared to be struggling with injuries as they came off.
“Declan [Rice] was feeling something, a sensation in his hamstring, so we won’t take any risks at 3-0,” Arteta explained.
He added: “The other is Gabriel Magalhaes. He had a tackle in the first half on his knee, and he was struggling. I hope [it’s not serious].”
