That's the view of former Fulham captain Danny Murphy.
He said, "Can he defend? Yes. He's quick enough, he's decent in the air and he's clever. Sometimes he steps in and tries to read the game or he drops off, he's not predictable with his defending.
"Also, he's a really good passer of the ball. I saw him live for the first time playing for Derby last year, I watched him twice. I said to Frank, 'What a player he is', and Frank said he's a real talent.
"He's just seamlessly transferred that form from the Championship to the Premier League, and at a time when Chelsea didn't start the season well, he went into a team that was under pressure and it was no problem. He's just adapted.
"He scored that wondergoal at Wolves as well, which shows he has technical ability. I would play him. I like him; he's calm and he's never on his backside."
