Kiwior spent 18 months in Italy with Spezia, making 43 appearances in all competitions. He still has three-and-half years remaining on his Arsenal contract with the option of extending the deal by a further 12 months.
He could be in line for more minutes in the coming weeks as Arsenal tackle a busy schedule. Takehiro Tomiyasu limped off during Saturday’s win over Wolves but Arteta is unsure how long it will keep the Japan star out for.
He said: “They (medical team) have to check him now. He was feeling a bit uncomfortable so we had to take him out.
“I don’t know (if it was his calf), he felt something, I don’t know if it was fatigue, we decided to change straight away with him, we didn’t want to take any risk. Let’s assess how he is.”
