Hughes, who is ready to hand Zouma his first run out in a Stoke shirt on Tuesday night at Sheffield United, said: "We're delighted. When you've had contact with players before – and I came close to signing him at a previous club when he was only 16 or 17 – sometimes that can help. You can say, 'I wanted you five years ago and now we've got an opportunity to get you to my club again and I want to do it.' That resonates with players sometimes.
"We're pleased. He's an outstanding player clearly. You don't sign an extension to your Chelsea contract unless you're very well thought of. We've got a very good player."
