It was yet again Chelsea who emerged victorious against bitter rivals Tottenham Hotspur, with Joao Pedro's first-half strike being enough to win it for Enzo Maresca's side.
The visitors showed a great level of intensity from the first whistle in this one, consistently catching Spurs in possession high up the pitch.
The home side, for large portions of the game, were shaky defensively and unable to sustain possession in more advanced areas. Too often were Thomas Frank's side made the easy pass instead of taking risks
Story of the match
It was a stop-start opening ten minutes into proceedings, mainly due to a head injury to Lucas Bergvall, who was eventually forced off the pitch after Tottenham's medical staff deemed he was not fit to continue.
Xavi Simons came on in his place, the Dutchman looking to make an impact against the side he looked like he was heading for in the summer.
As expected, Chelsea were enjoying plenty of the ball in the early stages of the encounter, but Thomas Frank's side looked more than happy for this to be the case.
It was made clear from the first whistle that this was going to be a physical affair. Both teams were putting in some firm tackles, but some fair ones.
Chelsea were the team on top in the opening twenty minutes, enjoying more of the ball and getting into some threatening areas. Enzo Fernandez was at the centre of a lot of these, particularly linking up with Alejandro Garnacho well down the left.
But Tottenham grew their way back into it, getting into more advanced positions but failing to create anything of real threat.
Joao Pedro had the first good chance of the game when Porro's blocked clearance rebounded to the Brazilian, leaving him one-on-one with Vicario. The forward's effort was saved by Vicario, but it felt like the home side was hanging on.
Chelsea kept up their intense pressing and eventually got their reward through Pedro. Moises Caicedo did brilliantly, charging down his man before winning the ball back and squaring it to the Brazilian, who dispatched his effort into the back of the net.
It was quite a half for Pedro, who could have had a brace in the latter stages of the 45 minutes. Gusto was found in acres of space, giving him plenty of time to deliver a threatening ball into the box that was struck first time by Pedro. Vicario did very well to make an instinctive save, ensuring the game did not get worse for his side.
Robert Sanchez was also called into action late in the half as Kudus's first-time shot was parried out of danger by the Spaniard, who made sure the ball would not fall in the path of the oncoming Djed Spence.
Chelsea would go into the break in control of this encounter. It was a much more impressive display from the Blues, who would be looking to pick up where they left off in the second half.
Meanwhile, Thomas Frank would not have been pleased with what he was watching in the first half, as his side looked incredibly shaky defensively.
Ten minutes into the second half, and things were not going any better for the home side. Frank's team talk had not seemed to have worked as of yet, as Chelsea were continuing to win the ball back with ease.
Most of the encouragement, albeit not a lot, for Spurs was created by Chelsea, who at times did not clear the ball as convincingly as they would have perhaps liked to.
Arguably, the Blues should have had a much more comfortable advantage by the latter stages of the first half, having created considerably more threatening chances than their opponents. In fact, they had not really given their opponents a sniff in front of goal on the night.
Groans around the Tottenham Hotspur stadium were a persistent theme of the evening, as the fans clearly voiced their frustration over the lack of intensity from their side.
Chelsea had two more chances in injury time as Jamie Gittens fired over the bar from point-blank range before Vicario denied Pedro yet again. The scoreline certainly flattered Spurs at this stage; it could have been much uglier than it was.
The full-time whistle blew to a chorus of boos all around the Tottenham Hotspur Stadium - apart from the away end, that is, where yet again the Chelsea fans celebrated a victory.
It was a mature display from the Blues, who, after a lot of disciplinary issues, certainly answered some questions in this encounter.
For Spurs, their torrid home form continues as the fans certainly made their thoughts on the match known to Frank and his players.
Player of the match-Moises Caicedo
It was another performance of the highest quality from Moises Caicedo, who just never slowed down from the first whistle in this encounter. The Ecuadorian made his presence known at the Tottenham Hotspur stadium, consistently winning the ball back in dangerous areas.
The goal summed up Caicedo's night perfectly, winning the ball back twice in quick succession, before setting up his teammate for the goal that won the Blues the game.
It was just another night in which the Ecuadorian ran the midfield, not allowing Spurs to feel any sense of control in this one.
