Liverpool boss Jurgen Klopp admits he loves the enthusiasm of Luis Diaz.
Klopp was asked today if anything from the January signing had surprised him.
He said: "I didn't know how much he enjoys training, I had no idea. I'm not sure I ever saw somebody like that.
"I said it before, he cannot stop smiling during training. He just can't stop. It's crazy. I didn't know that. All the rest, how quickly he would adapt, no, we didn't know that as well.
"They are all happy, all the players we signed in the last few years were all happy when they arrived here. It's not the worst place in the world, to be honest. Luis is now here already for nearly two months, or is it two months? I don't know exactly. That's rare how much he enjoys training, that's really cool."
