Pedri feels he will get his chance this season under the Dutchman.
"He makes a very good impression. He gave me playing minutes and that makes me extra happy of course," laughed Pedri, 17.
"It's the way we approach matches. We're doing well, we're putting on good performances. What Koeman says to me? He tells me to enjoy it, just like I did at Las Palmas.
"Keep him calm and don't get nervous about what might come next. He's a trainer who demands a lot of intensity from the players. I love that. Also the quick pressure when losing the ball. You can see that Koeman pays attention to the details."
