Arsenal boss Arsene Wenger says he will start with a strong line-up for today's FA Cup fifth round replay away at Hull City.
Midfielder Francis Coquelin is suspended with goalkeeper Petr Cech and defender Laurent Koscielny both ruled out because of injury.
19-year-old Alex Iwobi is expected to start for the Gunners after being included in Wenger's squad with the Frenchman happy with the versatility offered by the youngster.
"I have to rotate a little bit and keep the right balance in the team," Wenger said.
"I will have to but I'm not so much concerned about replacing one player with another one.
"We will play a team that has a good chance of qualifying, no matter who plays. David Ospina was an example of that on Saturday. I have the same respect for everyone and the same idea that all the players I have in my squad can play and win the game.
"I have told you many times that I rate Ospina as a world-class goalkeeper and I think he has been unfairly treated [since] I played him against Olympiakos.
"It was a time where his stats did not come out to the press and that's where I think he got unfair treatment. I never questioned his quality.
"We are in a position where we always have to win the next game. It is always the most important game of our life because it is treated like that by everybody else. That's the way we treat it. It's the most important game of the season for us because it's the next one.
"What I see in [Alex Iwobi] is a creative player who has a high work-rate and a good team spirit.
"I think he's a player who develops very well because he has a big passion for the game and he can score goals as well. He can play on the flanks, he can play through the middle, he's a very interesting player."
