The £88.5million January signing enjoyed a 35-minute cameo off the bench, going close twice to scoring and livened up a flat forward line.
It was Mudryk's first competitive action in 59 days and Potter was impressed by what he saw from the winger.
Asked if Mudryk was in contention to start, Potter said: "No, he's not played since November. Hasn't had any game time. It would've been a risk.
"He'll get better the more he is with us."
He added: "Sometimes people think us coaches turn top players into top players. But [players like] Mudryk understand the game. It's just fine-turning it a bit."
Fellow new signing Noni Madueke was not involved despite joining on Friday, and Potter has spoken of the £40million winger for the first time.
He added: “Now I can speak about him because he’s a Chelsea player. He’s an exciting player and brings a left-footed attacking option for us and competition in that area of the pitch.”
