Liverpool: Luis Suarez scored a dramatic late equaliser and controversially bit an opponent as Liverpool twice came from behind to draw 2-2 with Chelsea in a thrilling Premier League match at Anfield on Sunday.
The Uruguay striker headed home deep into injury time after Eden Hazard had initially appeared to have secured the points for Rafael Benitez's side on the Chelsea manager's return to his former club.
Earlier, Oscar's opening goal had been equalised by Daniel Sturridge.
However, the match was overshadowed by an off-the-ball incident when Suarez appeared to bite Branislav Ivanovic.
Before kick-off there was a minute of applause for Hillsborough campaigner Anne Williams as well as those affected by the Boston Marathon attacks.
Williams, who died last week, lost her 15-year-old son Kevin during the Hillsborough tragedy in 1989 and was one of the leading campaigners in the fight for justice over the disaster.
Liverpool carved open a chance in the fifth minute when Suarez slid a clever ball through the Chelsea defence for Glen Johnson to chase but the England right-back poked it wide.
Chelsea started to find their rhythm and shortly afterwards a neat passing move culminated in a shooting opportunity for Oscar who saw his near-post effort saved by Jose Reina.
The Liverpool goalkeeper did not look quite as comfortable in the 20th minute when he opted to punch away a speculative long-range effort from Ramires.
Benitez's side grew in confidence as the half wore on although it was a lapse in concentration from Liverpool defender Jamie Carragher which allowed Chelsea to take the lead in the 26th minute.
Juan Mata whipped the corner to the near post and veteran centre-back Carragher failed to track the run of Oscar who pulled away from goal to head past Reina.
David Luiz almost increased Chelsea's advantage two minutes later when Reina fumbled a dipping free-kick only to gather at the second attempt.
The hosts briefly threatened before half-time through Suarez, who tested Petr Cech with a powerful near-post shot which the Chelsea goalkeeper parried.
Liverpool manager Brendan Rodgers introduced Sturridge, a £12 million signing from Chelsea in January, for Philippe Coutinho at half-time and the striker had an immediate impact.
Sturridge put Steven Gerrard through almost from the restart but the Liverpool captain saw his shot saved by the feet of Cech and then struck the post with a shot of his own a minute later.
Liverpool's pressure paid off in the 52nd minute when Suarez curled a brilliant ball into the box which left Sturridge with a simple tap-in from close range.
Uruguay international Suarez then gave the initiative back to Chelsea five minutes later when he handled the ball inside the penalty area and Hazard confidently converted the spot-kick.
And shortly afterwards former Ajax striker Suarez, who was once banned for biting an opponent while playing in Holland, was caught by television cameras sinking his teeth into Ivanovic's arm.
Liverpool dominated possession in the remainder of the half but struggled to penetrate an organised Chelsea backline.
Suarez screwed a free-kick wide in the 68th minute and a good opportunity fell to substitute Jonjo Shelvey who shot wide from a good position late on after a brilliant backheel from Sturridge.
Inevitably Suarez would turn out to be saviour for the home side and he rescued a point deep into injury time when he headed home Sturridge's cross from close range.
