In the grand scheme of things, Jose isn't do that badly, so I can't be too critical. Second in the league, last 16 of CL, still in F.A. Cup, etc. However, a big part of why he was so poor in his second season at Chelsea was because of his inability to change things up.
To me, if something isn't working - and it quite clearly isn't at the moment, then change it. Whether that be system, personnel, strategies, tactics, etc.
We just don't seem to have any balance in our team at the moment - no game plan. We're playing like we've just put eleven players on the pitch and told them to play.
It's time to switch something up. If that means dropping certain players, then so be it.
