The thing is though, it happens maybe 5 weeks a season where clubs like us (ie non europe) play two games a week, include internationals say another 5. I would hope athletes out of say a 44 week season (thats allowing for 2 x months preseason) could play twice a week in 10 of those 44 weeks.
More than likely, players will be home and relaxed by 7pm saturday night after the Bristol City game, they wont go in Sunday or maybe go in for a massage. They will train monday, they will train tuesday with it probably being a lighter session going over tactics for wednesday, they may do a light session wednesday before making their way to Chelsea.
At this stage of the season they are just ticking over in training and fine tuning, they wont be run to death in training (even with Pulis) and its a sad state of affairs if players cannot do two games a week. If we were in europe then there is some justification for squad rotation, but for us, i dont think there is.
Clubs used to cope fine with it, and despite all the new sports science, ice chambers, etc i think there is still as many injuries today as there was 30 years ago! More maybe! I know football has moved on but i dont think this is about looking after the players, its solely about being on the gravy train.
