It's because he has grown a beard.
The only purpose of yesterday's fixture imo is to see who looked comfortable in that company , as it is a non starter as a competitive football fixture,Those that looked ok/comfortable:SenderosBakerCleverlyDelphN'ZogbiaThose out of their depthWeimannBacunaGrealishThe jury is out on the rest.
The beard makes Baker look like Mellberg that must be the key to his improvement right? I will admit I have only seen the highlights from yesterday, but from what I have seen I don't know if he did defend that well. It seem more a case of Guzan being in great form, City wasting chances, and a little bit of luck on our part why we almost got a point. Mostly, I blame Lambert for being too negative. A big reason why we beat them last season was because of how we pressed them in midfield, while still counter attacking effectively. Yesterday we got that balance wrong.
