Diaz is a good player. However, I'm not yet convinced how good he's going to be. He started like a house on fire, tailed off, got injured, came back and looked handy. As it stands, he still has it all to prove. I'm not sold on him being the ace that some people think he is. I hope he is FFS. But, who knows?
Certainly, he's not yet displayed any form like peak Mane.
