Chances were few and far between in an attritional derby against the Blues.
Asmir Begovic denied Harry Kane, Mousa Dembele and kept out our best chance from a Heung-Min Son header in the first half.
Eden Hazard headed over for Chelsea in the first half and then forced Hugo Lloris into the save of the match down to his left midway through the second half as it ended in stalemate at the Lane.
The result stretched our unbeaten run to 13 - one better than the previous Premier League mark set in the 2012-13 campaign.
“It’s always difficult to play against Chelsea and after travelling back from Azerbaijan (from our Europa League clash against Qarabag) it was an even tougher game but I think we can be pleased with the performance and the maturity we showed as a team,” said Mauricio. “The effort was unbelievable and for me, they are all heroes.
“We deserved more but at the end we have to be happy with the effort, we created more chances than Chelsea - I think they had one shot on target - and we can feel proud of the performance.”

Jose Mourinho later described it as Chelsea’s best team performance of the season.
“Chelsea played like a real team,” said Mauricio. “The effort, how they ran, the commitment, they showed respect and you only have to look at how Oscar, Hazard, Willian, Matic and Fabregas all ran, it was unbelievable.
“In the end, we can feel happy and maybe a bit disappointed because we always try to win. It was an opportunity at home but now we need to look forward and to be ready for West Brom.”
As for reaching the record 13 matches unbeaten in the Premier League, Mauricio said he was ‘proud and happy’ but as always, more interested in the future.
“It’s important, unbeaten in 13, but the most important thing now is to win against West Brom,” he added. “We need to follow in the same way, to keep working and always think towards to the next game.”
Meanwhile, Mauricio reported that Ryan Mason had to go off with an ankle injury in 10 minutes into the second half. He will be assessed tomorrow.
