Every PL winning team has players like him.
Except the Invincibles winning team of course.
I agree we need a solid base, and if we bought a top CB, as well as Torreira, and maybe an exciting winger, we would have that.
We would certainly have a decent forward line, and maybe with Emery’s attention to detail, adaptability and defensive organisation, which Wenger didn’t have, we might see us genuinely challenge for a top four place.
I’m not suggesting we can do what the top PL clubs do, but if we don’t do anything, we will fall further behind.
It’s easier to attract world class players if you already have some at the club.
It’s also easier to keep the ones you have if you buy that level of player.
