Fair enough, but he did misuse Haller trying to play him as a target man, one quick google and he could have seen the player was more suited too a three. We can just swap Haller for Danny Ings (who he did buy) who has hardly done anything there and was another poor buy. The two strikers you mention are just low grade target men, they suit his style of play and it relates to your other point in that I agree, you don't see many target men anymore mainly because they are bloody easy to play against that's why forwards now are more of a Watkins type where they can do a bit of everything. In terms of a team that's far more beneficial than a player who needs it handed to them on a plate all the time like DCL. Exceptions like Haaland who are just footballing freaks come along every once in a while though.
