Sunderland boss Gus Poyet can understand Chelsea's fury over their late matchwinning penalty.
The decisive moment arrived eight minutes from time as former Blues striker Fabio Borini scored from the spot.
Poyet, whose side moved to within three points of safety, admitted Sunderland were fortunate to be awarded the match-winning penalty: "If it was against me, I would have reacted the same..
"Emotion, key moment in the season, it could be the key moment for the title, that one.
"When it's for you, you feel you can see why he gave it. Especially the linesman when Azpilicueta goes down. 'But if it was against me, in a situation like that, I would have been fuming, for sure."
