De Bruyne, Delph, and Aguero seem to have the least obvious technique discrepancies between "stronger" and "weaker" feet in our squad. Can't think of anyone else off the top of my head right now.
As far as the topic goes, Dzeko's 4th vs Spurs is the one that immediately springs to mind.
Yaya as well - some great goals with his left foot - remember one in a defeat at the Emirates a couple of years ago.
