Former Celtic hero Patrick Roberts netted a dramatic 96th minute equaliser against Watford to keep Sunderland's play-off hopes alive at the Stadium of Light.
The Black Cats found themselves 2-0 down with 20 minutes to play after goals from Christian Kabasele and Scotland star Ryan Porteous had put the visitors in the ascendancy.
At that point, Sunderland's chances of playing Premier League football next season looked bleak. But Luke O'Nien handed the Wearside side a lifeline with an excellent finish into the bottom corner to set up a tense climax.
Sunderland dominated a whopping 70 per cent of possession and registered 25 shots at goal but struggled to make their advantage count until Roberts popped up with a huge stoppage time strike into the top corner just as the referee was ready to blow the final whistle.
