Aguero scored BIG goals for us, including the most important goal in our history. I don't think anything anyone does after will ever top that. It was a release of decades of failure, against our greatest rivals, with the last kick in the last game of the season. It was such an important goal that I don't even think Rodri's goal against Inter comes close.
Aguero was a magnificent player and had the lot - quick, skilful, created his own chances, scored against the big teams and did it for many years with us. He scored some brilliant goals and I only wish he'd won the CL as he deserved it. As a goalscorer, he had few equals and is easily one of the best players I've seen.
I do think Haaland though has the ability to become the greatest goalscorer of all time. The way he is smashing records is something else and he's a good 5 years from his peak. The way he is scoring, he's likely to break even records set in the 1920s!! I don't think I've ever seen a player with his size/speed/agility etc have so few touches but have such a big impact. I genuinely can't think of another player like him.
My view though is that Haaland won't be with us till he retires. I suspect his Dad, having been in the game, is probably quite cynical and wants his son to do well obviously, but looks like he's managing his career to some extent. I think he will leave us in a couple of years to go to Real. My gut feeling is that we won't see peak Haaland.
I just feel very lucky to see these 2 players play for us. Both have scored incredible goals and loved smashing United :)
