Chelsea's unbeaten start to the season continued on Sunday afternoon after beating London rivals Tottenham 3-0 to move top of the Premier League table.
After a largely uneventful first half, Thomas Tuchel made a halftime-change, and it had an immediate impact as early goals from Thiago Silva and N'Golo Kante set them on the path to an important win on the road before Antonio Rudiger rounded off the win late on.
The first open chance fell to the hosts in the 23rd minute after the referee played advantage when Dele Alli was fouled, allowing Heung-Min Son to spin the ball around the corner for Reguilon, who sprinted before finding Lo Celso in the centre but Antonio Rudiger made a vital block.
Both teams had half-chances to find the back of the net in the remaining minutes of the half, but none could, even though Spurs enjoyed much of the possession.
The second half saw Tuchel make a change and a tactical switch, replacing Mason Mount with Kante and changing the team's formation.
The Blues then took the lead inside the opening four minutes of the half when the brilliant Silva rose highest to meet a Marcos Alonso corner ball and powerfully beat Hugo Lloris at the far post.

Spurs then failed to offer any resistance as the Blues shred them to pieces, coming close again in the 53rd minute when Alonso forced a goal-line clearance.
Chelsea's persistence paid off once again as they doubled their lead in the 57th minute, this time substitute Kante with the goal.
The Frenchman was accorded time and space after Matteo Kovacic found him with an easy ball, and he unleashed a shot from 25 yards out which deflected off Eric Dier and past Lloris off the post.
The visitors continued creating more chances but somehow the scores remained 2-0 until the last minutes of added time when they got their third.
Rudiger combined well with Timo Werner to score with a striker's finish low into the bottom corner, giving Lloris no chance.
The win saw the Blues move top of the table alongside Liverpool with identical records after five rounds of matches.
It also saw Tuchel's side reach a record sixth consecutive league away win in a London derby.
Meanwhile, having lost to Crystal Palace last time out, Spurs drop to seventh on nine points.
