Chelsea boss Thomas Tuchel insists they deserved their 3-1 victory over Southampton.
Chelsea scored two late goals as Tuchel's side bounced back from consecutive defeats to beat winless Southampton and move top of the Premier League.
Timo Werner and Ben Chilwell struck in the final six minutes after Saints had been reduced to 10 men following the dismissal of captain James Ward-Prowse for a poor challenge on Jorginho.
Academy product Trevoh Chalobah put the hosts ahead after nine minutes, swooping at the back post to head in his second of the season after Ruben Loftus-Cheek flicked on Chilwell's corner.
A dominant Chelsea had the ball in the net on two further occasions in the first half, however Romelu Lukaku was flagged offside and Werner's header was ruled out following a foul by Cesar Azpilicueta on Kyle Walker-Peters in the build-up.
The hosts were punished for not extending their advantage when former Chelsea player Tino Livramento was tripped by Chilwell in the box and Ward-Prowse fired in the resulting penalty.
However, the visitors could not hold out for a point following the loss of their skipper, whose yellow card was upgraded to a straight red after referee Martin Atkinson viewed the pitchside monitor.
Afterwards, Tuchel said: "It was deserved but it was a long way to go [to get it]. I liked the game, it was very entertaining with two intense sides. I liked the energy and the attitude. In the end we got the result right which is always the challenge and the target. It was a late one but a deserved one."
On Timo Werner's disallowed goal which was ruled out by VAR due to an earlier foul by Cesar Azpilicueta, the manager added: "Is it really about time or is it about situations? It's more about where it is, do you have a chance, can you re-group? I [made] no connection from this challenge to the goal. I thought they were checking Romelu's header from when they landed.
"The connection for me was not clear enough that from the challenge we get the possibility to score. The referee must have the freedom to let it go if he decides to have a fair, physical game. This is one of the challenges and I understood before the season it would be like this."
