Chelsea goalkeeper Petr Cech admits facing former boss Andre Villas-Boas added interest to Saturday's derby at Tottenham.
Spurs boss Villas-Boas met the Blues for the first time since he was sacked by owner Roman Abramovich when his new club hosted the Premier League leaders at White Hart Lane.
But his hopes of revenge were dashed as Chelsea emerged 4-2 winners to maintain their four-point advantage at the top.
However, Cech, 30, insists the presence of Villas-Boas in the Tottenham dugout did not provide any extra incentive to beat their north London rivals.
"Us players did not take it in such a way," the Czech international told his official website.
"Perhaps it was more special for the managers because Andre and Roberto Di Matteo worked together at Chelsea last season.
"The presence of Andre surely made the atmosphere more spicy.
"Before and after the match he said hello to us, he shook hands with everyone and we exchanged a few words. It was nice to see him again."
Cech admits his superb save from Tottenham defender Kyle Walker's shot, as the Blues led 3-2, proved crucial for Chelsea to continue setting the early Premier League pace.
"David Luiz put his leg there, missed the ball and I saw it at the last possible moment," he added.
"I had to react quickly. If Tottenham has made it 3-3, who knows what would have happened.
"Fortunately it was us who added a fourth goal from a counter attack."
