Tottenham 2-0 Chelsea: Oliver Skipp and Harry Kane combined to secure Spurs' first Premier League win over their London rivals at the Tottenham Hotspur Stadium.
Chelsea have struggled with injuries so far this season and their bad luck continued when Thiago Silva limped off after just 19 minutes to be replaced by Wesley Fofana.
The home side took the initiative after the interval, and Skipp netted his first senior goal for the club to give them the lead after 46 minutes.
Kane then doubled his side's lead in the second half, finding space at the back post to add to his Premier League tally for the season.
