They have continued to surprise us and have won over the hearts of the national team supporters."They have a strong chance of progressing to the semi-finals of the tournament, because they now have the confidence of facing any team on the continent."The important thing is for the whole nation to be behind the boys. They deserve our support because they are doing the country proud."De Sa picked up one cap for South Africa during his playing days and also acted as goalkeeping coach during the reign of former Bafana boss Carlos Queiroz.
