He scored one and created an assist in the win over Burton, and has now recorded four goals and three assists in his last six games for the Foxes.
"Youri's an excellent player," Davies said. "He's a pleasure to work with, he's got a top-level mentality in the way he approaches the game.
"Everything that Youri does is quality: the way he lives his life, the way he focuses, tactically, his intelligence on the pitch, the way he can solve problems on the pitch, he's very coachable, he's a good team-mate.
"He's got a lot of qualities. And there's more to come from Youri. He will get better. You saw his power in the first half, driving away from people, setting up the goal. He was excellent.
"With Youri he's got this real focus. He's in the gym, he's doing his work, he's preparing his body constantly for competition. Hopefully his good form can continue and he can develop even more."
