Rajevac said Amartey was excellent despite the centre-back occupying the right-back position in the two crucial games, which Ghana won.
Philemon Baffour was the only natural right-back in the team after Reading FC player was ruled out with injury, but the Serb opted for Amartey.
“We couldn’t get Andy Yiadom to camp due to injury and when I was making a game plan for Zimbabwe, because I wanted a very offensive midfield and attack, I decided to put some players in defence and have others in the back so we protect ourselves for an important result so that is why our defence was pretty tall.
“Daniel has played that in the past, he even played in a defensive midfield position so he is a versatile player and he is a player I can trust and I knew he is up to the task so he delivered excellent performance and he said also he is ready to do whatever it takes to take Ghana to the World Cup and follow my instructions so everything went well,” Coach Milovan Rajevac said in an interview with the Ghana FA media team.
Following the back to back wins, Ghana remain one point behind South Africa and must win their remaining games to top the group.
They will return to action in November with games against Ethiopia and Bafana Bafana.
