Arsenal manager Mikel Arteta lavished praise on young winger Bukayo Saka this week.
The Spanish head coach was pleased with Saka's display in a Champions League group stage win over PSV Eindhoven.
The winger was at his best, scoring and assisting in a convincing 4-0 home win.
Post-game, Arteta stated: “Yeah, but to be fair some of the boys do play international level and have big roles for the national team.
“You can sense that, that they are not just part of the squad, they have responsibility and they're big players there. That's very helpful for the team."
On German attacker Kai Havertz improving, he added: “Yeah, he was really connected today in the game.
“It's true I asked him to play two different roles in regards to the behaviors of the opponents and he's so intelligent that he does it. It's just finishing one or two actions that we had but it's coming in and he's so willing to do it."
