Fatigue has been a problem for years.
Ive said for quite some time the players are knackered. This season you will see so many more I juries than usual and the fixture list ahead ( domestic and international) is,imo, enough for top players to make them feel deflated. If we don't listen to the players there will be major problems.
I believe the problem is huge, and I can't prove it,but I think there are more than a few players over playing or feigning injury just to get rest.
Big squads will mask the problem. Short term. At City KDB seems unable to last 90 mins now. At Chelsea the unbelievable fitness issues from last season has contnued into this. Their captain James recklessly got himself sent off at the tail end of the season ,had all summer to rest, somehow picked up a hamstring injury during the summer ...and is still out to this day. Rodri has been complaining for a while now. The injury lists around the premiership tell their own story ,early on, a few weeks into the new season..at a time when, historically every squad member was fit and raring to go, full of hope for the new season.
I'm rambling now ,but to answer your specific question.,the issue of weather the players can strike is redundant in my view.... some will effectively be dropping to their knees ,physically unable to play unless something is done about it. Akanji spoke recently about retiring soon to avoid the future fixture list...he was apparently joking but his description of the upcoming schedule for him personally ,makes you think.
This is a serious issue , one we were all warned about a few years ago by the Belguim national coach who articulated his fears and concerns for KDB a nd him being burnt out. I posted the coaches comments on here and got laughed at.
No one is laughing now, not least the player himself. Rodri is in the same boat.
There is too much football. And not enough rest.
Haaland looks a man transformed after his summer off. ..
