He may well have been sincere but if you're going to 'ffs' people repeatedly while making a point that doesn't really stand up to any scrutiny then glib is probably a fairly polite response to be honest.
I'm not really a fan of just pretending last season doesn't exist to make his stats sound better either really, but even if we do it doesn't change the point at hand. As I said, this isn't me saying he'll be a waste of money, only time will tell on that score, it's me saying i can see why people aren't sure that he was the right profile of player to be signing at this moment in time.
