Liverpool failed to make significant inroads into Chelsea's lead at the top of the Premier League table after two Jermain Defoe penalties earned Sunderland a point in an absorbing 2-2 draw at the Stadium of Light.
Having cancelled out Daniel Sturridge's opener, the former England striker was again on target from 12 yards after Sadio Mane was penalised for handball having earlier restored Liverpool's lead.
And Defoe may feel it should have been a hat-trick of spot-kicks, with Emre Can having gone unpunished for an earlier handball in the box.
Mane looked to have snatched the three points when a loose Papy Djilobodji header presented him with a tap-in after 72 minutes, but it was his arm that stretched out of the Liverpool wall from a Sebastian Larsson free-kick to gift Sunderland the equaliser.
