Why because I didn’t mention any players in the same positions as you have. So my argument is only valid if the scenario is exactly the same to what we have witnessed so therefore I’ll never have a valid argument?
To keep it plan and simple then. Injuries should never be an excuse in football. It’s lame, every club has injures.
Every club has injuries - but some people have more or if than others. But yes - that could be down to poor preparations from the club (wrong training methods, wrong type of players, wrong playing-style) - or it could be down to bad luck.
If 5 players get hamstring injuries - there's usually something wrong at the club. If 5 players get freak injuries or get injured due to nasty tackles - it's bad luck.
But if a club get 10 injuries - of course it matters. The problem is - if a club has a complete squad - a well worked-out playing system (which you only get from a few years of playing in the same style) you can cope. You can get a youngster up from the reserves, or play a player out of position for a few matches. But even with the best of clubs if you get too much - you can't cope. In addition - the managed needs to know the players 100% - so he knows which players can do what. Ferguson knew that - Klopp and Guardiola probably do as well now - because they have at the club a long time.
I remember some matches with Ferguson where we had to play a make-shift defence with Fletcher and Carrick - and were destroyed (i Think Fulham did it to us once) - in other matches we could play Park and Rafael in midfield against Arsenal and win. Sometimes it works - sometimes it doesn't!
We are not there - we don't have the squad for it, we haven't implemented a playing-style yet, and OGS doesn't know the players well enough to know who he can trust (but I think he is getting closer)
So you can say that every club has injuries - and it shouldn't be used as an excuse - but every club also has that one player - or two, which they can't replace. If Liverpool get van Dijk and Mane injured long-term - they will still be a very strong side, but they won't win the League. If City lose Sterling and Aguero - same thing. Strong, but they wont win the league.
And when we lose Pogba and Martial - in addition to a lot of other injuries - it hurts us. It's not an excuse - but it's an explanation.
