If we're not going to sack him immediately, we may as well keep him till the end of the season. He's been a complete flop since day one. We sat here laughing at the likes of Liverpool and Spurs for wasting millions upon millions on average players, when we're absolutely guilty of the same mistakes. di Maria, Herrera, Rojo, Memphis, Mata, Fellaini Schneiderlin, Bastian and Darmian have all been flops, thus far. Each player (maybe not Rojo) went from a world class/good player to waste of money in the space of a few months. And that is firmly down to the manager. That's discounting the fact that he's let the likes of Hernandez, RvP, Nani, Kagawa, Januzaj, Wilson, Evans and Rafael all go when they may have been useful to us, this season.
Honestly speaking, I'm not surprised by the problems we're facing, at the moment. The moment the transfer window closed and we failed to bring in a striker, winger and a centre back, it wasn't hard to foresee the issues we could be facing by Christmas. The lack of quality in our team is a crime. All this money spent and we can't even beat Bournemouth (wow), in addition to have such a thin squad, most of which are made of glass. Our opening game against Spurs set the tone, for me. A summer had passed, 100 million was spent and we continued from where we left of at Hull, the season before. Boring, dull, unimaginative and, quite simply, crap.
As for the improvements:
14/15: PL 16; W 9; D 4; L 3; GF 29; GA 17; Points 31 ~ 5 goals were conceded in the freak game against Leicester.
15/16: PL 16; W 8; D 5; L 3; GF 21; GA 12; Points 29
We've already started declining before we started improving.
