I take commercial is hinting you will have such a rager the night before that you will wake up so late in the day next, leading to your breakfast being essentially lunch/dinner menu, otherwise wtf
Who overrates them? Pochettino did a great job with Spurs (best defence due to his coaching), was few games from competing for title until the fucked it up. And Bilic has rejuvenated West Ham, stellar job and making them play good technical footie in a side thats used to Allardyce hoof ball lol. He cant be overrated considering he has done more then expected, same thing with Pochettino, where after this crazy excellent season, at the end its seen as just ok to get a CL spot. With friggin Spurs of all clubs.
But yeah Koeman is fairly mediocre, and Mazzarri is lolsy.
