Thomas Tuchel wants Chelsea's players to continue proving their quality after watching them run riot against Norwich City.

Shorn of the injured Romelu Lukaku and Timo Werner, Chelsea made light work of lowly Norwich at Stamford Bridge, with Mason Mount scoring a hat-trick in a 7-0 win.

It was the fourth time Chelsea have won a Premier League game by seven or more goals and the first time since December 2012 against Aston Villa (8-0), with only Manchester United netting seven or more goals in more Premier League games.

Mount opened and rounded off the scoring, with strikes from Callum Hudson-Odoi, Reece James, Ben Chilwell and an own goal from Max Aarons wedged in between.

Chelsea's win lifted them four points clear at the top for at least a few hours, and though pleased with the display, Tuchel wants the same level of performance when the Blues take on Southampton in the EFL Cup on Tuesday.

He told BT Sport: "Yes, a good performance, we were sharp, put in a lot of effort.

"High-pressing, [we] played a high rhythm and created a lot of chances and we were very precise. It was a deserved win. To score seven you need a bit of luck and momentum, but a good game.

"This will not stop, this is only one game and the next one follows on Tuesday here, up for a challenge again and they will have to prove it again. All the credit, but it's only one game."

Mount had not scored since netting in a 2-0 Champions League win over Real Madrid in May, but he was the star of the show against the hapless Canaries, who also had Ben Gibson sent off.

He had more shots (five) and efforts on target (four) than any other player, while his tally of three key passes trailed only Mateo Kovacic (six).

Tuchel said: "It's good, because no matter what the coach says and how many good opportunities you have, how satisfied the coach is, the offensive guys need goals to feel fully happy, full confidence.

"He waited long, too long, and it was good that he got some goals today."

Tuchel had concerns about fatigue with Mount, and he added: "I don't think it was a matter of now he is fresh and yesterday he was tired. For now it's a process, we are still in between international breaks, I think it's normal. It's a status that will not change from one game to the other.

"I agree that today he looked fresh and it was good to put him on the pitch. We need to be careful with these players ... who play important roles in their national teams and have a lot of competitions."

Mount added: "Before the game I was putting pressure on myself to get on the scoresheet because it's been quite a long time since I did, and then three come around in the same game.

"I don't think I've ever scored more than one in a game for Chelsea, so it's obviously a massive moment for me to get three, I'll remember this for a long time.

"You put pressure on yourself. I was always getting in the positions to score, but I just wasn't putting it in the back of the net, and I just thought there'd be a game where it was going to come off and today was the day.

"It was my luck today, and obviously the team as well, not just me. The way we played today, I spoke before about intensity, an early kick-off, being at it from the beginning and we were like that today."
