Mate, there's a middle ground between replying with "phenomenal" to every question and generally talking out your arse, and openly disclosing sensitive business matters because you want to reply bluntly to every question.
It's just called being professional about certain things. There's room for "no comment" - he doesn't owe the press an answer about confidential business matters.
Look, if he gets asked about a transfer target, he shrugs his shoulders, right? Because it makes professional sense to do so, because you don't want to disclose important or sensitive information? The same thing should have happened here - it's just common sense.
