Missing Players and team news:
Slavia defender Ondrej Kudela served a provisional one-match suspension in the first leg amid investigations of racist abuse, but the defender did not travel with the squad in any case due to illness, and he was not involved at the weekend either. The Czech giants only had one fit centre-back for the first leg and will remain without David Hovorka (knee) and Simon Deli (COVID-19) for this battle, so goalscorer Holes may be forced to deputise in the heart of defence again. There are also fresh concerns over Peter Olayinka and top scorer Abdallah Sima, who both missed the Prague derby due to “health problems”, but Trpisovsky will hope to welcome the two attackers back for the second leg. Arsenal’s two creative hubs in Martin Odegaard and Emile Smith Rowe are considered major doubts as they nurse ankle problems, while Bukayo Saka’s involvement is also up in the air due to a thigh problem he picked up at Bramall Lane. Arteta is optimistic that Aubameyang will recover from illness in time to feature, and Martinelli has shrugged off his own injury worries, but Kieran Tierney and David Luiz remain in the treatment room. Should Saka, Smith Rowe and Odegaard all miss out, Dani Ceballos could feature in a more advanced midfield role after impressing against Sheffield United, allowing Granit Xhaka to return to the middle of the park as Cedric Soares deputises on the left.
