I 100% get your point, I just don't get the bigger picture.
I'm thrilled to see us more recently using our academy regardless of why we had to. So we sell Tomori for £30 million (maybe it's Euros) just my opinion but I think he is worth more to us as a player to develop, particularly alongside Silva than that amount of money, which we now have to spend in excess of to buy in a player to replace Silva and Tomori.
I'm sure Tuchel has his reasons, and he has just guided us to champions league victory so I'm not as qualified as him to make assertions.
