There are Xmas parties every year, so this one doesn't stand out as anything particularly special....
....that said, it does 'feel' like the 'spirit' of this team is not the same as it used to be. I appreciate that this is not an evidenced opinion, but is instead based solely on intangible perceptions - but to me, this current crop of players doesn't 'feel' particularly tight-knit.
For example - If I was in a bar fight - I would have been confident that the likes of JT, Lamps, Essien., Ballack, Diego C, Rudi, JFH, Eidur, Wisey, Jody M, Kerry D, Azpi, Alonso, Kova, Giroud, cahill, Luiz, Alex, Brana, Riccy, (to name but a few we have had over the years) , would have had my back.
With this current lot, I am not sure there is much fight in any of them. Connor would get stuck in. Disasi might. Nico Jackson would probably lose his head and glass someone... but the rest of them? I am not sure.
