Ghana coach Joe Nana Adarkwa says praise and incentives have helped restore the confidence of the Black Maidens as they prepare for their Round of 16 clash against Argentina at the FIFA U-17 Womens World Cup in Morocco.The Black Maidens suffered a 3-0 defeat to Norway in their opening Group C match but recovered to draw 3-3 with Brazil before securing a 2-0 victory over Canada to book their place in the knockout stage.Adarkwa said the players remained determined to keep their World Cup campaign alive despite their disappointing start to the tournament.When we were in camp, you could see from their faces that we didn’t have to go home and that we’d win the game and stay. And lo and behold, it happened, he said.The coach explained that his technical team prioritised encouragement and positive reinforcement, while also providing incentives to lift the players morale.We praised them because, for our girls, you have to praise them all the time before you let them know their mistakes, Adarkwa added.We gave them some incentives to boost their morale, and now you can see that everything is on top; their spirit is on top. We’ll wait and see what happens in Wednesday’s game.Ghana will face Argentina at the Mohammed VI Football Complex in Rabat, with a place in the quarter-finals at stake.The Black Maidens will be aiming to maintain their improved form and extend their stay in the competition after showing resilience to recover from their opening defeat.Adarkwa will hope the confidence gained from their performances against Brazil and Canada can inspire his side to overcome Argentina and secure a place in the last eight.
