I agree he was a dumb signing, but certainly not because he is not a great player. He is. But we keep singing players that require better management to get the most out of and at the same time we keep pretending Valverde is a great manager. It's like you buy a great tasting fish, but you have a dumb chef trying to fillet it. And he butchers that fish to the point that all it is left is 20% of its meat.
Come on, you are trusting Bartomeu with all the signings? He doesnt know shit about football as well. Since when do we have to resort to so many big money signings; it's ridiculous. No one is denying Valverde is a terrible manager, but Barto is part of the problem. He is resorting to more senseless signings, partly due to Valverde's woes. You could say both of them are bringing the entire club down.
Griezmann is neither like Firmino or Tadic; I don't care how he does for Atletico or France, where he basically has the free-man role all to himself. That's where he can roam without restriction. In Barca, you have Messi who innately expresses his creativity and false 9 abilities, with dribbling superiority. How is Griezmann supposed to co-exist when his main ability is roaming as well.
Firmino has attributes of close dribbling and clinical finishing. Powerful and clinical and has the technique for it. He merely played a false 9 role which requires dropping deep but overall he is a much more superior striker than Griez. Griezmann is more solely dependant on movement and always has been. He is also weak in being both footed. If you want him as a CF, you need to have powerful strikes, and is able to score in various positions. It's a misconception strikers only shoot from the middle, modern strikers now is able to shoot from left right centre, but evidently Griez is incredibly weak in that area. He is more used to picking up loose shots and try to put it in the back of the net. But asking him to score a goal after Messi pass along the flank he will struggle. Not to mention he is also weak in getting past defenders.
I suppose you can ask a coach to "develop" him in that area but he doesnt have the acceleration to beat defenders, he is more accustomed to staying behind the lines of defence. A coach can only develop a player BASED on his abilities and attributes. Another thing that can be developed nowadays is decision making which is what many players lack. You can tell Messi to play like Ronaldo or Ronaldo to play like Messi that's just impossible. Pep made use of Messi's abilities and played him as a false 9.
