Just about every team has 3 strikers they find it quite helpful when playing a 4,4,2 formation, having a striker on the bench to freshen up the attack, having 3 strikers means that when Aguero is knackered or injured as he is going to be for most of next season and Jesus goes off from we do not have to rely on a teenager, or a winger, i do not know about you but i like a winger to play as a winger and a goalkeeper to play as a goalkeeper, they tend to play better there, As for Haaland i recon he would be the same as Aguero maybe not as clinical but a better target man.
