FC Edmonton’s Sinkgraven and TFC’s Winter will forget their friendship during NCC clash 26 Apr 2011 Harry Sinkgraven and Aron Winter know each other well. They played against each other in the Dutch league. They were in classes together as they worked towards getting their coaching certificates. And, both are working to bring the Dutch 4-3-3 style to their respective teams. Winter’s Toronto FC and Sinkgraven’s FC Edmonton will face each other Wednesday in the first leg of their Nutrilite Canadian Championship semifinal at Commonwealth Stadium. But, once the first ball is kicked in anger, the friendship between the two will evaporate.
