The striker, Ghana's most important player by many people's reckoning is facing a race against time to get back in shape for the opening game on January 24 against Botswana and for the subsequent games in the campaign.
And the Ghana Football Association desperate to have Gyan available are engaging the services of Kovacevic who has worked with Arsenal striker Robin Van Persie in the past and the Black Stars at the World Cup to speed up Gyan's recovery.
"The head coach has spoken to me about her and talking about her history she has been able to heal more Premiership players and during the World Cup she worked with us and according to the players it worked so I can't wait to meet her," Gyan said on arrival in Accra from his UAE base. "Maybe it will work because I also want to play in the Nations Cup; I want to help my country. It's been a while since we won the trophy which is what everyone is expecting.”
Gyan picked up a second degree hamstring injury in a league game for Al Ain last week and is at least two weeks away from being able to run and train again with the ball.
Medical sources within the Black Stars are confident he will recover in time to play a part in Ghana's campaign but admit the opening games against the Zebras of Botswana might come too soon for the striker.
Gyan has a goal scoring rate of a goal every two games at international level for Ghana and scored three times enroute to the Nations Cup. He scored six goals out of Ghana's tally of nine at the 2010 Nations Cup and is deemed fundamental to Ghana's campaign especially with goal scoring traditionally Ghana's major problem at international level.
