Pitch-side microphones picked up Tuchel's rant at Werner while the game was goalless.
The forward appeared confused over his position as he occupied the left wing for a period of 15 minutes.
The Blues manager wasn't best pleased with his star man's position as he wanted him on the right wing.
He reportedly shouted: "Timo, how much longer do you play left? You play right. You've played left for 15 minutes. Do you not understand?"

Only good thing about empty stadiums is hearing what managers say & Tuchel was having none of Werner:
"Timo, how long are you staying on the left? You're playing on the right! The last 15 mins you've only been on the left! Don't you understand?"

Werner eventually took Tuchel's instructions on board with his team beating Everton 2-0 at Stamford Bridge to continue the new boss' unbeaten start at Chelsea.
Under Tuchel, Werner has seen an upturn in his form though goals remain hard to come by having scored just two in all competitions since November 8.
Chelsea, meanwhile, stay in fourth place after goals from Ben Godfrey (own goal) and Jorginho either side of the break.
On the £71 million man, the ex-Paris Saint-Germain gaffer said: "I am very pleased with Kai. It was the trust we gave him and he used that trust.
"He has all the ability to be a dominant figure in [attack] and he stepped up.
"He showed up between the lines to accelerate our game, increase the touches in the box, be responsible for assists and through-balls, and take responsibility to finish himself.
"There is no doubt about his quality, his talent and his character."
Tuchel has not lost in 11 games in charge since replacing Frank Lampard in January.
Next up for Chelsea is Leeds at Elland Road on Saturday.
