Arsenal goalkeeper Petr Cech is set to make his Champions League debut for the club against Bayern Munich on Tuesday night.
Arsene Wenger had opted to play David Ospina in the Gunners' two previous European fixtures - shock defeats to Dinamo Zagreb and Olympiacos - as he tried to keep both of his keepers happy.
However, Ospina's performance in the 3-2 home reverse to the Greek outfit left many Arsenal fans seething with their manager and demanding Cech be reinstated.

Reports had suggested Ospina would consider leaving north London if he was dropped for the vital fixture against Pep Guardiola's side, leaving the Arsenal boss with a tough decision on his hands.
But the choice has been made easier for Wenger after the French boss revealed his Columbian number two will miss the game.
As per the Mirror, the 65-year-old revealed Ospina had returned from international duty with a shoulder problem, paving the way for Cech to start his first European fixture for the Gunners.
He said: "Ospina is out injured. He has already been out. He came back from Colombia with a shoulder problem and he is out.”
Defeat would almost certainly spell the end of their Champions League campaign for another year. However, failure to reach the knockout stages may not be a bad thing for Wenger and his side - providing they avoid the Europa League.
The lack of midweek football could be a blessing in disguise for the Gunners, who are in a strong position to end their long wait for a Premier League title.
