Chelsea remain eager to exact revenge on Tottenham for the "football lesson" they received in the Premier League last month, according to Gianfranco Zola.
The two clubs will meet in the semi-finals of the Carabao Cup in January after coming through tricky last-eight ties on Wednesday.
Eden Hazard's late winner gave the Blues a hard-earned 1-0 win over Bournemouth and set up a London derby date with Spurs, while Manchester City will meet minnows Burton Albion in the other tie.
Tottenham ended Maurizio Sarri's unbeaten start in English football back in November, storming to a dominant 3-1 victory at Wembley Stadium, and Chelsea's assistant coach revealed that result remains a source of frustration.
