Ghana coach Kwesi Appiah has warned his players not to get carried away after they narrowed the gap to one point in the Group D campaign in 2014 FIFA World Cup qualifying.Asamoah Gyan, Mubarak Wakaso, Majeed Waris and Agyemang Badu scored to help the Black Stars currently second, secure six points after beating Sudan 4-0 in their fixture on Sunday in Kumasi.As Zambia dropped points in their 1-1 draw at Lesotho, Ghana piled on the pressure at the top and also improved their chances of upstaging the leaders to the summit.But Appiah has insisted there will be no margin for error as his side look to maintain their winning run.“The most important thing is to win all our games and that is what matters now,” Black Stars coach, Kwesi Appiah said.“I have always said that it doesn’t matter whether Zambia is leading the group or not, the most important thing is to win all our matches and that is what we (Black Stars) are doing now.”Despite his side's convincing win over Sudan, the Black Stars coach believes they still have a long way to go.“I believe tactically the players were really disciplined and they played their best to get the win for the nation.“The team is in a building process, we are trying to get a winsome side.“There were a few lapses which are normal but we will make sure we make amends in our next game but overall the performance was really good,” said the Ghana coach.Ghana will travel away to Sudan for the reverse fixture when the qualifiers return in June.
