Fans are fickle in general but many of you turned on the player quite easily
I don't think so. Even those who rate him very highly aren't blind to his deficiencies. When he plays badly, as he has recently, naturally the conversation is going to focus on those deficiencies. That's not "turning on him". And that goes without saying many people always had reservations about the player and didn't rate him all that highly to begin with.
I struggle to remember the last time he succesfuly passed a player with a dribble.
Individually, some of his traits, like his dribbling, are nothing special. He’s not fast, he can’t reliably beat his marker, his conversion rate is pretty average and I certainly wouldn’t call him an above-average finisher. Also, if I'm not mistaken, he's scored 3 and missed 3 of the 6 penalties he's taken for us, so we clearly can't consider him a great PK taker either.
Obviously, he does have some great attributes, his tenacity, anticipation and teamwork in particular - you can't teach those things. When he puts it all together, you have a fantastic modern striker. In that sense, he’s very much a “package” player. However, when he fails to put it together, for whatever reason, you see how weak certain parts of his game are when isolated and exposed.
Someone like Dzeko can blow hot and cold with his finishing. However, his hold-up play is
always top notch, without exception. Even if his finishing greatly fluctuates, Dzeko is smart enough to keep it simple, and play to his strengths to help the team. That makes him always a valuable asset. On the other hand, when Lautaro is having an off-day, he's an utter detriment to the team. Taking stupid low-chance shots from tight angles, diving, fouling and in general losing the ball with every attempted play. Obviously Dzeko is vastly more experienced but Lautaro needs to learn to do the basics right when he's not on his A game.
