Robin's Chocolate Leg

From a story in the Daily Express, which I came upon because I don't want to write this stupid memo and am procrastinating:

Van Persie is renowned for his twinkle-toed skills and the venom of his left-foot shooting but he has been concentrating on his “wrong” foot recently – and is convinced it is paying off. He said: “I know I can shoot with my right leg. Of course my left one’s better but it’s down to your belief in the power of your wrong leg. In Holland we call it your chocolate leg.”

Van Persie...added: “Positive thinking is the key for me – when I have a chance I think positively. I think this is a good chance with my right foot – I can score this one. And I think you will miss many more chances with your chocolate leg if you think negatively, thinking that it’s not your strong foot."

Chocolate leg. That's cute, and there is he is, scoring with his.
