From what i've seen of Audero this season he is far from the finished article.
Seems a fine shot stopper but has looked very unsure when dealing with crosses and more questionable when he has the ball at his feet and has to distribute under pressure. Necessary stuff for a modern GK.
Doubt we would get much cash from him now and he certainly isn't up to snuff to be our 2nd keeper.
And the Brit press article I found discussing Audero claims Arsenal are interested because he will be a free agent this summer which isn't even true
