Too many pretty players with no end product. Marko, Lallana and Coutinho have nothing on Silva, Navas, Oscar and Hazard.
Too many mediocre players, and that's what you get when you buy ass loads of cheap potentials, mixed with a couple of mid table quality. Also there's something seriously wrong with our defensive coaching, it's just a circus at the back every time any team puts in any kind of attack.
