What's abnormal about it though is the fact that he didn't bother to inform the club of his condition when he was on vacation. They could have started his therapy since then rather than waiting about a month for him to return in order to operate.
At times like this you really appreciate players like Buffon in your team, ones that are more hungry to serve the club than spending a week more on fuckin vacation. All that while keeping in mind that Vicenzo barely played a game last season and should be the one looking to make up for Juve rather than rest his lazyass.
