The 25-year-old Italian played his part in Wednesday's 2-1 Capital One Cup fourth round victory over Southampton.
Mannone said: "Of course I want to keep my place, that's why I came here.
"I've been hurting on the sidelines, so I was really happy to take my chance on Saturday and do well for the team.
"It was a really good win last night and I was involved in a good performance. I want to push on.
"Obviously it's down to the manager but I'm available for him and I will push as hard as I can in every single training session and every single chance I get out there.
"This manager is very open to performances, he likes to watch the game and he will pick what he thinks is the best side.
"It's not down to me, the manager has an opinion. But hopefully I've done enough to show I can play in this team and I want to push on to be number one. That's why I'm here."
