The difference I have noticed is that we are a bit more direct than under Mancini, Yaya doing lots of not very accurate long passing. The defence seems to have gone from a pretty tight unit to a shambles.
What both Manuel and Roberto haven't seemed to grasp is that even Barca might struggle against Cardiff and their ilk.
We have several players who to my mind would be better in La Liga. Yaya, Silva, Edin. Not saying they are bad players.
We also have players who seem designed for the EPL. Milner, Negredo and Navas. Admittedly the last two have only played twice. But Navas has pace and Negredo is physical. Dzeko reminds me of Le Tissier. He is a bit of a soft boy. Lots of skill, great goals BUT...
We need to move the ball much quicker, this will allow Kun more space to use his speed and skill.
I reckon this may have been a shock for our new manager. Hope he learns quickly.
