Definitely more Agüero than average. Won us the league all by himself. To give you a current comparisson, what he did last year down here is way better than what Lautaro did when he got sold to Inter. Imho, he's a much better player than Lautaro but you never know how South American players will adapt to football and life in Europe. Players that did great here go and flop in Europe, and players that did mediocre here go and become stars in the old continent. So you never know.
Little known fact about this guy: when he was 11, he tried out for Madrid. Scored 5 goals. Madrid wanted to keep him, but they couldn't because Álvarez was too young.
