Throughout the season former player Clive Walker provides radio and TV commentary on Chelsea's games. Here he selects five aspects from another derby day to cherish that caught his eye…

1. It was such a lovely, open game and Chelsea came out on top, showing a great deal of character in the second half.
We showed a quality that maybe at other stages, last season especially, we didn't have. Any team that wants to win the Premier League has to have it and on Saturday we showed we have players in the squad who get their heads down, continue to play some super football and also have finishing ability. Juan Mata is on fire at the moment.

2. The Chelsea players pressurised Tottenham very well when they had the ball and when Spurs tried to pressure us in the first half, they couldn't get near us. Our pressuring was going to draw some mistakes from the opposing side but it also left the game on an edge while we were only 1-0 up. When it went it to 2-1 to Spurs, they played very similar to us, very open, which always gave us the opportunity to get back into the game. In such a flowing, open game you always thought we had more quality to score goals than they did when they kept it open. The work-rate we put in as well gave us the opportunity to score more goals.

3. You always want goals from every position on the pitch and we have 14 different goalscorers already this season. Gary Cahill has been immense when he has come in, he has hit the ground running every single time and the volley he scored was as good as any centre-forward could manage. Marco van Basten came to mind the way he struck it. It took a slight deflection that might have taken it away from Brad Friedel but the power was tremendous.

4. Spurs switched players rather than change formation at the start of the second half. They tried to get Clint Dempsey into the game more, and it worked to a degree, but Chelsea alsogave them too much time and space on the ball. They came flying out the blocks and we weren't ready for it. There was a lack of discipline. We were shellshocked by the two goals and it took time to get back on track but thankfully we have the players to turn games back around again.

5. In the build-up to Mata's second goal the movement off the ball was terrific and the run by Mata was superb, but for Eden Hazard to play it first time to him was even better. When a team are patient in possession and waiting for the killer pass, more often than not it will come from a first-time ball and they don't come much better than that one. It was on to Mata's left foot, perfectly weighted.
