No it doesn't make him clueless it just means he's revealing what he'd like to happen. Schadenfreude is after all one of the defining characteristics of being a football fan. Maybe you're a lot more kind hearted than I am but if a club who i didn't particularly dislike but who had been dominating football for years suddenly found itself potentially in a spot of bother i'd definitely hope that some misfortune befell themBecause we haven't been found guilty of anything yet; hoping we get relegated at this point in time makes him look like a bitter clueless prick.
As a neutral it's kind of annoying to watch other clubs celebrating if it happens too often. Look at Arsenal ........ City fans don't really give a fuck about them but it did become very annoying last season to see them celebrating so often and i think the prevailing mood amongst blues now is that it'd be fun if their dreams turned to shit
