LONDON -- Maurizio Sarri's unbeaten start to the season as Chelsea head coach was shattered in emphatic style by a rampant Tottenham at Wembley, as Dele Alli, Harry Kane and Son Heung-min all found the net in a 3-1 win. Had the home side been more clinical, this would have been a humiliation as well as a rout.

Positives

Nothing. Chelsea were outplayed from start to finish by a team who, at best, they consider domestic equals. If you really wanted to find a silver lining, Olivier Giroud's injury-time consolation was nice, and more than Alvaro Morata did in 58 minutes on the pitch.

Negatives

The "mental problem" of starting games too slowly that had troubled Sarri was in full display at Wembley, as Chelsea simply didn't match Tottenham's intensity or aggression. Concerns about Sarri's system being too defensively open also came home to roost with a comical number of gilt-edged chances for the home side.

Manager rating out of 10

3 -- Sarri knew going into this match that his Chelsea players had lacked a mental edge in recent weeks, and part of an elite coach's job is to correct that. There was also no real suggestion that he has a tactical Plan B if it becomes obvious that his starting system has been compromised and overrun.

Player ratings (1-10; 10 = best. Players introduced after 70 minutes get no rating)

GK Kepa Arrizabalaga, 4 -- His least convincing performance since arriving at Chelsea. Alli's header to break the deadlock went straight through his hands and though he was unsighted for Kane's second, his positioning also gave him no chance. His defence offered no protection for Son's third.

DF Cesar Azpilicueta, 5 -- So often Chelsea's steadiest performer, Azpilicueta has struggled for consistency in another new role this season and he couldn't do much to help his team here -- even if he did supply an inviting cross for Giroud to score a tidy, but meaningless, goal.

DF Antonio Rudiger, 4 -- Better than David Luiz, but that isn't saying much. Kane gave him the runaround and the fact that he was booked early on dulled his trademark aggression.

DF David Luiz, 3 -- This was the kind of night his critics always point to. His concentration and positioning were awful throughout and his two worst contributions -- twisting out of the way of Kane's shot and committing himself needlessly against Son -- put the game beyond Chelsea.

DF Marcos Alonso, 4 -- Chelsea's poor passing meant that rather than being an attacking outlet he was a defensive liability, repeatedly getting caught too high upfield when the ball was lost. Son exploited the space vacated by him to great effect for Tottenham's third goal.

MF N'Golo Kante, 5 -- Tottenham's policy of making him the one Chelsea midfielder they didn't press in possession paid dividends, as his distribution was inconsistent and rarely incisive. Even his usual energy couldn't make up for the deficiencies of those around him.

MF Jorginho, 4 -- Very sloppy in possession from the outset. Normally relishes being pressed but Tottenham's attackers were able to force him into mistakes that put Chelsea on the back foot. Out of possession his lack of mobility was brutally exposed by Son for Spurs' third.

MF Mateo Kovacic, 4 -- Contributed to Chelsea's poor passing early on as Tottenham seized control and he couldn't find a way to positively influence the game. On the rare occasions that he managed to attack the penalty area, his finishing proved typically wayward.

FW Willian, 4 -- Picked over Pedro for this game presumably because of his defensive work rate, he could not prevent Tottenham from slicing through Chelsea's first line of pressure and nothing he did going forward led to anything substantial.

FW Alvaro Morata, 3 -- Simply wasn't a factor in the match at any stage, not least because he spent much of his time offside. Did not have much to work with but he also gave those tasked with supplying him very few options. Hooked by Sarri before the hour mark, with Hazard shifting to false nine.

FW Eden Hazard, 5 -- Should have been awarded a penalty when he was felled in the box by Juan Foyth, and his good moments provided Chelsea's only threat in a torrid first half. Deployed as a false nine for the first time this season by Sarri in the second, but the game was long gone by then.

Substitutes

FW Pedro, 5 -- Generally did OK in possession without threatening Hugo Lloris' goal or creating any huge danger, but both teams knew it was over.

MF Ross Barkley, 6 -- Brought on when the game was already lost, he clipped in one dangerous cross that Kante was too small to divert goalwards.

FW Olivier Giroud, 7 -- Came on for Willian as Chelsea switched back to a conventional striker system with 15 minutes left. Scored a nice goal.
