I actually don't think we have too many midfielders. We need 6 high quality starters for 3 slots. We saw what happened last season with the number of games and injuries. Zubimendi dropped off a cliff toward the end of the season because he was playing 90 minutes 3 times a week for 4 months straight. I know there are 8 players listed there, but the last 3 (and indeed MLS) all play other positions too so will get plenty of game time.
We'd have to get a massive offer for MLS that allowed us to buy an absolute star on the left wing for me to be ok with selling him.
Yeah it feels like they just watched a bunch of other films that came later, took the best bits, and glued it all together. They even took popular memes and recreated them verbatim into the film. I suppose that's what Hollywood has become now in 1942.
