I mean, the vitriol, and not just on this board, borders on the ludicrous. Every striker we're talking about signing is from a lower tier than the elite bracket. Every single one. Some, I'd say, are even lower tier than Lacazette even, yet they are offered up as better alternatives. Maybe it's just because he's the most likely signing, and folks are getting themselves riled up to hate on Wenger, Gazidis, Kroenke et al when/if he proves underwhelming?
They guy knows what he's doing on a counter attack, which is more than I can say for any of our current players bar Ozil. He also knows how to play in the center at point, he's not a conversion project. He scores goals. He can dribble past a man, make run off the backs of players, and hold the ball up. He's tough. He's not big enough to be a great header of the ball, but that's what you keep Giroud around for. His main asset is his intelligence, which normally Klaus likes in a player, but for whatever reason not in this case. He's always aware of what's around him, and always looking for a route to goal. Because of this, he can keep defenders pinned back and keep the space between the lines free for Ozil/Sanchez/Ramsey to exploit.
His game is rooted in the basics. He's not got a lot of personality/flair on the pitch, but he plays the right pass or turns his man more often than not. He's good in tight spaces, can keep the ball right under him, he's no kick and run type like Walcott or even Wiltord. He's very functional in his ball skills, and has just enough to get the job done.
He's better than Perez, Walcott, Welbeck, and Giroud (overall). He's more proven as a forward and a goal-scorer than Mbappe or Morata. By far. He's better than Lukaku in every aspect of the game apart from those that deal specifically with size, and in terms of hold-up, he holds his own regardless. Costa is a cunt. Icardi as well, but I haven't seen anything that suggests he's any better than Lacazette either. Both play in crap leagues and its impossible to say how they'd adapt. Schick shouldn't even be in this conversation.
I would sign Aubameyang over Lacazette, sure. I'd sign Mbappe regardless.
