Sergio...
Much better all around striker for me....Can Haaland develop to be that....possibly
Sergio was better outside the box, shooting from distance, link up play. Probably better one one one with a defender as well.
Haaland better in the air (though for his size sergio was very good)
Haalands movement in the box is probably slightly better than Sergios - borderline however.
Sergio however had that ability to consistently score goals out of nothing, impossible angles and in the tightest of spaces...i dont think Haaland has that as much ...his athleticism allows him to get to balls that possibly Sergio wouldnt get to BUT think of a couple of sergios goals vs the scousers.....I dont think Haaland scores either of those especially the one at the near post....or the utd goal where he runs across the goal and beats the keeper at the near post.
Haalands ability to be int he right place at the right time (reading of the game) - better than Sergios probably.
I think Sergio strikes the ball better than Haaland over all
