I honestly don't know!
Yaya's was just a fantastic strike that very few players in the world could have done. Plus it was quite unexpected as we'd spent so much time passing the ball from side to side without much threat, that he just pulled that out of nothing. No one on the pitch knew what was coming except Yaya.
But the second goal was a fantastic team move - from Kolarov's header back to Pantilimon, to the superb finish from Nasri.
Those 90 seconds were simply phenomenal. Completely turned the game on its head, and despite Sunderland not giving up, it did knock the wind out of them.
