Petr Cech emerged from Arsenal's nail-biting win in Moscow to admit he still loves the thrill of European football and wants to keep David Ospina out of the team when it comes to the semi-final.
Cech is the club's senior goalkeeper but this season manager Arsene Wenger promised his deputy the chance to play in all cup competitions.
Ospina twisted an ankle in training ahead of the first leg against CSKA and was initially ruled out for two or three weeks.
'We will see what will be his decision for the rest of the competition,' said Cech, after playing in both legs of the Europa League quarter-final, putting the onus firmly on Wenger.
