As long as Buffon is available and inform, he should and will play.
Any goalkeeper coming with the ambition of benching or succeeding buffon, while he is here, is a major idiot and deserves the bench.
I mean, who on their sane mind would come here at the prime of his career to try and bench buffon of all goalkeepers. Better wait for the old man to retire and then come with your curriculum in your hand.
Or just accept your support role and do not bitch about it.
Its simply too risky careerwise otherwise.
