Watford boss Gianfranco Zola is delighted with the form of on-loan Chelsea youngster Nathaniel Chalobah.

The teen started for the Hornets on Saturday in their 2-2 draw against Bristol City, earning rave reviews. He is on loan at the Championship side until the start of January.

"I thought for 25 minutes, or 30 minutes, he was quite outstanding," Zola told the Watford Observer. "His performance was really top class and he played well when he also went to the back.

"He is a player that if he maintains the right attitude and keeps working and focusing on learning then he could really become an important player. He can go as high as he wants to.

"He has all the qualities to become a top player but he just needs to work hard every day and not lose the desire to work hard in training."
