Chelsea boss Mauricio Pochettino admits he enjoys working with Mykhaylo Mudryk.
Pochettino is pleased with the Ukraine winger's progress.
"He's a fantastic guy and he's such a nice person," said Pochettino. "He's very authentic and genuine. One thing I can tell you, he's very honest and very trustworthy and a very genuine and spontaneous guy. I trust in him as a person, of course.
"And then as a player he knows he needs to keep improving. He's still young and he is going to improve, because he has the quality. He's a player that in his evolution is doing really well and we are so happy.
"For sure with time he's going to be a very important player. He's already an important player but he's going to improve a lot because the potential is massive."
