Defoe's was brilliant strike, can think of a couple more contenders off top of my head, Mata volley and a very good team goal that Schurler finished off for Chelski
I think the quality of the strike,(on his wrong foot) the fact it was a derby game, the huge significance in context of the relegation struggle, Then Defoe's will take some beating
Adam is bound to win. Zamora's was special too. Defoe strike will be downplayed but we know it was sensational. There was a rocket from QPR Phillips too at Palace
