Chelsea hero Ashley Cole was delighted for two-goal Kai Havertz after victory over Fulham.
The German midfielder scored twice against his side's local rivals at Stamford Bridge, helping Thomas Tuchel's men to close in on Champions League football next season.
Havertz has had a difficult start to life in England since arriving for £89million from Bayer Leverkusen last summer, scoring just eight goals and providing eight assists in all competitions.
Cole said: "He was fantastic.
"He didn't get too involved in the build-up but his little through balls and deft touches and control around the box, I think he deserved his two goals."
Ex-Fulham boss Chris Coleman was also impressed with Havertz and backed him to have a successful career at Chelsea.
He added: "I was very impressed with him. His little deft touches and his intelligence, knowing when and where to run, and then when the ball arrives he's not flustered, and all the top, top players have that.
"They always seem to have more time on the ball. He's still young, and he's going to be better and better."
