Suarez can be immense, he's a goal scoring machine, but often against small teams. He gets criticized for sometimes not showing up against the bigger teams though, which is something that can happen, because you can't shine every game, but the 'big' teams in the Dutch league aren't exactly world beaters.
I've seen him quite a few times and 90% of the time he seems ready for the big stuff. That's purely based on what I've seen.
If you look at his stats, for a player his age, they're nothing short of impressive. I'd take him.
