Everybody operating at the highest level is cooked. This isn't an Arteta problem. It's a problem of misaligned greed amongst the Premier League, the FA, UEFA/CAF/CONMEBOL, FIFA and even the teams themselves. Everybody has seen a fat turkey upon the table and they want to grab a leg, a wing, or a breast for themselves. And for us, we are experiencing this in two dimensions, which is what makes it harder -
a) we are a better team now than when Arteta took over, so naturally we will play more games, but
b) Infantino and his friends are all adding more games. There are the 6 Euro Nations League games that used to be meaningless friendlies, there are 4 more Champions League games, there are more teams and an extra round at the World Cup, and Afcon also recently went 24.
The only thing clubs can do is get bigger and bigger at this point. And not just an extra Norgaard. We need an extra Rice or Odegaard
