Eden Hazard's run of scoring form continued at Hull as he netted his fourth goal since Christmas, an eye-catching strike that broke the deadlock in the 2-0 win on Humberside.
Having now equalled the nine goals he scored in the league the whole of last season, the Belgian spoke after the game of the importance of his opener.
'The first half was very difficult,' Hazard said.
'We know playing away to Hull is always difficult but in the second half we worked hard and we scored two goals for the three points. The manager said at half-time - no stress, continue to try to be the best - then the first goal was good and helped the team to be on top.'
Fernando Torres scored the second goal to ensure Chelsea moved to the top of the table ahead of Sunday and Monday's fixtures.
'Now we can recover for two days and we can watch Arsenal and Man City, and we are on the top of the league and we are happy,' said Hazard.
