13' Jorginho's long ball is headed clear only as far as Mount, who plays a pass into Werner's feet. But the Germany international miscontrols. We are still waiting on a first chance at either end.
11' Tottenham's average positions so far have only Lamela in their own half. Eight Chelsea players have been stationed on halfway or further forward.
9' Tottenham have grown into this game a little, pushing Chelsea back into their own half. The Blues have had by far the greater share of possession but done precious little with it.
7' Bergwijn rolls Jorginho on halfway to prompt a first Spurs break, but his pass to Lamela gives Zouma the opportunity to step in and clear.
5' Chelsea have not quite found their range. Hudson-Odoi swings over a cross that clears the head of Werner, who is then given a chance to deliver and does exactly the same, failing to pick out the England winger.
3' Azpilicueta goes long in attempt to isolate Tanganga up against Werner, but the Chelsea captain overhits his pass. Tottenham can enjoy a spell of possession for the first time.
2' Playing against quite a defensive Spurs set-up, Chelsea quickly assume control.

Let's get the team news...
Tottenham were given a bye through the previous round after Leyton Orient failed to fulfil the fixture due to positive coronavirus tests, although their schedule remains manic, with Maccabi Haifa visiting Tottenham Hotspur Stadium for a Europa League play-off in just two days' time. Meanwhile, Chelsea thrashed Barnsley 6-0 last week to set up this tie.
The two London rivals endured contrasting fortunes at the weekend, yet both came away from matchweek three of the Premier League with just a point. Spurs dominated Newcastle United but saw a controversial late penalty award go against them, while Chelsea battled back from 3-0 down at West Brom to earn a draw. Attention now turns to the cup and this fourth-round tie.
