Almunia has established himself as the club's first choice for the first time in his Arsenal career, with Jens Lehmann having been openly critical of Arsene Wenger's decision to resign him to the sidelines.
While Lehmann remains disgruntled, Almunia has spoken of being in a 'privileged position' between Arsenal's posts.
"I am in a privileged position to be in a team which is playing the best football in Europe at the moment," said Almunia to the club's official magazine.
"It is unbelievable sometimes when we score goals and the defenders come back to take up their positions again - I say to Kolo [Toure], 'how on Earth did we do that?'
"I just know I have to play well in each game and do not like to look into the future too much.
"If I am thinking about January or February in the next game I could make a couple of mistakes and be back on the bench.
"Football is very cruel - and especially with goalkeepers. That is why it is such a difficult position to play.
"At the end of the day we are all human and not perfect - everyone makes mistakes in what they do and people have to understand that."
