Fireworks were expected for the second leg of Chelsea and Tottenham's Carabao Cup semi-final at Stamford Bridge on Thursday night.
Harry Kane's penalty separated the London rivals two weeks previously at Wembley, so a strong start was needed from the hosts.
And that's exactly what they produced as N'Golo Kante opened the scoring in the 27th minute with a half volley from outside the 18-yard box.
Toby Alderweireld's headed clearance at a corner fell straight to the Frenchman, whose strike squeezed between three sets of legs and past Paulo Gazzaniga.
Spurs' goalkeeper should have really done better, but the pace of Kante's shot and the sheer amount of bodies in the way clearly made it hard to judge.
Eleven minutes later Chelsea doubled their lead through Eden Hazard as the Belgian met Pedro's cross and found the bottom corner.
Everything was going the Blues' way as Tottenham struggled to create much without their two star players, Kane and Dele Alli.
Mauricio Pochettino cut a frustrated figure on the touchline and there was one incident early on where the Argentine had a go at Chelsea manager Maurizio Sarri.
In the 10th minute, a strong tackle from Eric Dier left David Luiz in a heap and Sarri reportedly reacted by waving an imaginary yellow card at the fourth official standing next to him.
Sarri wanted punishment, but Pochettino didn't appreciate the Blues boss gesturing a yellow card to get his player booked and went to confront him.
The fourth official managed to break them up and rightly told Sarri not to do it again.
Players waving an imaginary yellow card to get opponents book is frowned upon in the Premier League, so it's no wonder Pochettino was angry with Sarri.
Tottenham later made it 2-2 on aggregate through Fernando Llorente's headed finish in the 50th minute to send the game to penalties.
