A crushing three-goal victory away to London rivals, a clean-sheet and top of the Premier League – that's still not enough for Thomas Tuchel, who blasted Chelsea's first-half against Tottenham.
The Blues failed to create a proper scoring chance in the first-half on Sunday, and were pegged back for long spells as Nuno Espirito Santo's side came out swinging.
Enter N'Golo Kante, who Tuchel picked to replace Mason Mount at half-time before watching the Frenchman flip the match in Chelsea's favour. He took control of the midfield and scored the Blues' second on his return from injury.
