Defoe, who scored the winner, took three shots, had a pass accuracy of 85%, created one chance, put in one cross, and made two blocks.

Vito Mannone was superb today. Crucial saves at crucial times. Kaboul excellent. #safc— Pete Whalen (@petewhalen7) May 7, 2016

Just beautiful. Defoe. Khazri. Borini. Kaboul and Borini put in so much effort. Epic game #safc— pom pom anemone (@redandblacksky) May 7, 2016
Mags say Defoe is the only difference, not true, passion through the team in Kone, Kaboul, Kirch, Khazri, Fab to name a few helps too! #safc— Luke Wrightson (@LukeWrightson) May 8, 2016
Jermain Defoe has scored a goal every 164 mins in the PL (15 goals). Better than Mahrez, Costa & Lukaku .... decent! Help keep #SAFC up!— Rizwan (@Riz1Ahm3d) May 8, 2016
