Mason Mount said Chelsea should have finished off struggling Tottenham long before the end of their 1-0 Premier League win. 

The victory for Thomas Tuchel's visitors to the Tottenham Hotspur Stadium came thanks to Jorginho's first-half penalty, awarded after Eric Dier hacked down Timo Werner. 

By failing to capitalise on a host of chances, Chelsea rather let Tottenham off the hook and the hosts had a couple of late openings that could have led to an equaliser. 

There was no doubting Chelsea were the superior side, however, as they climbed to sixth, four points behind fourth-placed Liverpool. 

Mount said: "We should have scored more in the game. I had a couple of chances, we had a couple of other chances where we should have been way more clinical in front of goal. 

"That's something we need to work on, myself as well." 

Mount enjoyed an advanced role as new head coach Tuchel tinkered with his line-up, and the England midfielder spoke positively about the experimentation. 

He told BT Sport: "It's new for some of us players, especially me today, maybe playing a bit as a false nine, dropping into the 10 and helping the midfield out. 

"We're all learning but it's going well so far. I didn't have my shooting boots on today so that's something to work on during the week."

Tuchel saw his team dominate the first 45 minutes but Tottenham had more of the ball after the break, albeit without looking anywhere close to their best. 

"Minute by minute we lost some of the ball possession," Tuchel said. "But whenever we lost the belief, we never lost the structure and the intensity to defend. 

"In football there are many ways to have a good performance and if it's necessary to suffer, you have to be ready to suffer and that's what I'm very happy about." 

Chelsea have taken seven points from their three Premier League games under former Paris Saint-Germain boss Tuchel, as many as they managed in their final eight top-flight fixtures under predecessor Frank Lampard. The previous Blues boss to have clean sheets in his opening three games was Mourinho, all the way back in 2004. 

Still, Tuchel sees scope for improvement: "A bit more killer instinct would have been nice because it would have been possible to decide [the game] in the first half. 

"Also, in the first 15 minutes of the second half and maybe during the whole match, there were chances where we lacked a bit of determination in the box and the last touch. 

"But it's like this - it's best if we have something to improve and we still win, and it was a big win in an away game and that is very, very good. I'm very happy." 

He spoke about his players buying into his way of playing, and how they "live it 100 per cent". 

"We never got too passive, too deep in the field," Tuchel said. "We pushed and we had many one-on-ones to isolate the opponent and not give options. 

"For that you have to be brave, and we were brave and winners in the end. It was deserved and it feels great."
