Chelsea hero Joe Cole believes manager Thomas Tuchel made "a statement" with his introduction of Timo Werner for victory at Burnley.

Tuchel went with Werner as a second-half substitute instead of Romelu Lukaku against Burnley. Chelsea ran out 4-0 winners at Turf Moor on Saturday thanks to four second-half goals.

"Chelsea just blew them out of the water, as you would expect with the quality they have on the pitch," Cole said on BT Sport Score.

"Reece James, outstanding, can't sing his praises highly enough.

"I think Pulisic came into the game, Mason Mount came into the game, Havertz with two goals.

"I think he's better as a No 9, a false nine. He looked like a penalty-box player today which I feel he is. He comes alive and he'll score many [goals].

"I think what was telling today is that the fact Chelsea were three or 4-0 up and Thomas Tuchel looked at his bench and Werner came on, Lukaku didn't. I think that's a statement.

"If you're a manager and you're trying to manage your squad, that's an opportunity for him to come on, maybe tap another one in and build himself up. But he didn't.

"But it's a great win for Chelsea on the road."
