Zambia's head coach Herve Renard of France shouts to his players from the sidelines during their final African Cup of Nations Group A match, against Equatorial Guinea at Malabo Stadium in Malabo, Equatorial Guinea, Sunday, Jan. 29, 2012. Zambia defeated Equatorial Guinea 1-0.

MALABO, Equatorial Guinea — Zambia coach Herve Renard isn't taking any chances with his clothing at this year's African Cup of Nations, and so far his trusted lucky shirt seems to be working.

Renard has sported the same white shirt for all three group matches — a 2-1 win against Senegal, a 2-2 draw with Libya and the 1-0 win against co-host Equatorial Guinea which clinched top spot in Group A on Sunday.

Renard says the superstition dates back to his time in charge of Zambia at the 2010 African Cup when he changed his white shirt for a blue one after an opening win against Tunisia — only to lose the second game to Cameroon.

Despite the sweaty climate in Equatorial Guinea, Renard says he "won't change" and insists hygiene is not a problem because the shirt is washed after every game and "is very clean."
