FABIO BORINI scored a dramatic late equaliser to earn Sunderland a draw that keeps their hopes of avoiding relegation alive.

Andre Ayew opened the scoring for West Ham before Wahbi Khazri equalised for the Black Cats direct for a corner - only for them to allow Collins to restore the Hammers lead two minutes after the break.
Then Borini came up with the vital equaliser in stoppage time, and there was still time for Sam Byram to besent off for his second yellow card.
