While him leaving would be a good thing for team cohesion, in my view at least...and also I'm trully starting to dislike him, we live in real world not Hollywood fantasy.
In fantasy world we would sell "a bad" guy, recive money, strengthen our squad and win everything showing him "our way". But in real world we'll lose a great player (he has tactical errors that a good coach can deal with), hugely talented player and end up throwing all our money on player like Coutinho. We'll get milked all the way by Liverpool and will end up with good player but neither Ney on the wings nor midfielder maestro. Forget about Verratti in a deal. PSG, or I should say Qatar, have the money for 10. Neymars...they are just dancing around FFP, but there is no way they will buy Ney and then sell Verratti.
Again, in real world, YES, money will buy you CL and all other titles...maybe not in first or second try but if you have enough money you'll get there.
This is the road football is going and we must deal with it.
What angers me in our club is complete lack of sporting and scouting divisions. We can't and won't be able to compete with "oilers", we also have our style of play which is a gamble sometimes. I actually belive our style is the reason why RM is able to sell big while we are not. For example Paco would score some headers if he played in RM, some tap-ins and voila - you have a 50 mil attacker for Arsenal! In our team a player either fits or looks like amateur comparing to others. For example Gomes would probably looked much better in RM, here he looks like a cruel joke.
But, what is our scouting team doing? They had a whole year to prepare and they come out with freaking Verratti??? Really, Verratti? Even worse, no B plan? BVB wants 100 mil for Dembele? How much did they pay for him and where were we then? Seri, Keita even Mbappe...even Ceballos we looked at him after everyone else spotted him. We had Xavi-Iniesta and all of the time in the world to start thinking about post Xavi-Iniesta midfield...years have passed and we came out with Arda or Gomes! I'm scared about post Messi era!
