Arsenal boss Unai Emery hints Petr Cech will be rested for Thursday's Europa League tie against Vorskla.
“We are going to change and use a lot of players for different competitions, but only thinking about the best performance for us to win on Thursday," he said.
"Every competition for me is about [doing as well as you can] and normally you use a different goalkeeper in those [other] competitions, but it's about giving [your best] performance."
The Gunners will start their campaign against FC Vorskla Poltava at the Emirates, before then facing back-to-back away games against Qarabag and Sporting Lisbon.
