Chelsea legend Gianfranco Zola hailed the performance of Mateo Kovacic for their 0-0 draw at Brentford.
Zola praised Kovacic's standout display on the night.
"He's a player that has become very consistent," said Zola. "First of all he barely loses the ball, he's always in control and under pressure you can pass the ball to him, he never loses it. He's always very creative.
"He's a player who has improved so much playing in that position.
"I have to say fair enough to Thomas Tuchel; he played him in that position and it suits him so well."
