In my opinion Arsenal ruined him. He could have been much better for them, but at first there wasn't enough talent around him. Later they bought Auba for his position and made Lacazette second fiddle to him. That was a huge mistake in my opinion. Always thought Lacazette would have been a brilliant striker 'false 9' for Barcelona. After Suarez left Barca didn't have money otherwise I'd definitely have gone for him at the time. Great technique and a good finisher as well. Obviously in the end of the day, whatever the circumstances, Lacazette has now been underwhelming for too long. Don't see him getting back to elite level anymore, but I do feel a lot more was in him if Arsenal had build their new team around him, instead of moving him around and making him second fiddle.
