The contest didn't yield too many chances, Heung-Min Son seeing our best opportunity go begging when his first half header from Harry Kane's cross was kept out by Asmir Begovic in the Chelsea goal.
Hugo Lloris made one superb low stop in the second period to deny Eden Hazard and, with few real clear-cut chances following on from that, the spoils were shared.
We're now 13 games unbeaten in the Premier League - a new club record.
