Arsenal will be hoping the pair are fine as they are next in action on Tuesday evening, when they travel to Slavia Prague in the Champions League.
“I think that was one of the best games he (Gyokeres) has played,” said Arteta. “I think overall his performance was exceptional.
“Everything - his high press, his position and his touches. His running in behind, the way he linked play, the way he got us from this situation to transition moments, a lot. I think he was in a really good moment.
“It’s a shame that he felt something. We had to take him off because he was feeling a little niggle. So we’ll have to wait and see.
“He felt something muscular so we have to wait to learn the extent of that.”
On Zubimendi, Arteta said: “He asked to be subbed, so we’ll have to wait and see.”

“The first half was exceptional, we scored two goals and gave nothing away,” said Arteta. “That was the platform.
“We had to make a few changes and didn’t have that much control in the second half. The defending was exceptional again, we didn’t give anything away.”
