Well, actually...
A statement about future possible events is never going to be 100% true or 100% false, unless it's a tautology or oxymoron respectively. The gregster not only qualified his statement by stating it as 'opinion' - he also included a proviso as to future events that would establish the truth of his claim.
Even worse, at the moment, Benitez has no 'current success' at all -therefore whatever favourable reputation he has is most certainly based only on 'past glories' at this time. So your claim that he is not 'living on past glories' until some future date, because it also contains an untrue claim about the present, is demonstrably untrue.
Scouse Logic... sucks.
Brilliant
