Well, the injuries have completely defined the season at this point. On this international break alone Gomez, Henderson, Rhys Williams, Shaqiri, Alexander-Arnold all came back with injuries. I think you can see how someone would be royally pissed about this. We've also had other players hurt for the majority of the season at this point. I agree with what you're saying about Minamino, but Mane and Salah are the two players who never get hurt regardless of how many games are being played. It's everywhere else that we're having some problems.
Considering that we've played at least one midfielder in defense for the entire season so far, and considering we've had three midfielders hurt for almost the entire season thus far, it's at least pertinent to this season that we can't rotate. Also, Klopp did rotate a lot in the last two seasons. Especially in midfield. Regardless, I think when you keep getting players who get injured or get covid from internationals, and then you rehab them and send them back to internationals before they can even play for their club, and they come back and get hurt? I think this happened to both Tsimkas and Keita. It seems grossly unfair to all the teams that this can happen.
I think it's fair to keep complaining in the hopes that the season will be lengthened two or three weeks, or that any international breaks prior to the Euros will get cancelled.
