Ghana, who have been rocked by injuries at the Africa Cup of Nations, finally had some good news with the return to fitness of Anthony Annan for tomorrow's semi-final against Nigeria.

Annan, who plays his club football in Norway with Rosenborg, has had to watch Ghana's progress to the last four from the sidelines, missing the 3-1 loss to Ivory Coast, and the 1-0 wins over Burkina Faso and Angola.

Serb coach Milovan Rajevic, speaking at the team hotel in Luanda yesterday, confirmed: "Anthony is recovering well and we can use him in the semifinal."

Annan's recovery could not have come at a more appropiate time as Ghana prepare to face Nigeria in the West African derby.

The two sides last met in the 2008 Africa Cup of Nations quarter-finals, with Ghana prevailing 2-1 only to go out 1-0 in the semifinal to Cameroon.

Rajevic has done wonders to get the limping Black Stars to the last four in Angola with stars like Michael Essien and Stephen Appiah among a raft of key players unavailable.

He has had to rely on a mix of inexperience, with eight members of Ghana's Under-20 World Cup winning squad called up for senior duty, and just a few established players such as Annan and Asamoah Gyan.

Gyan scored the decisive goal in Ghana's quarterfinal win over the hosts in Luanda last Sunday and the Rennes striker is relishing facing Nigeria.

Gyan said: "Every Ghanaian knows how important it is to play Nigeria. We are ready for them and prepared and we will stick to the game plan that the coach has mapped out for us.

"We beat Nigeria two years ago. We have a lot of young guys in the team but we are committed and focused and will do everything possible to win."

Rajevic may be a blow-in from Serbia but he is acutely aware of how important victory over neighbours Nigeria is for every Ghana football fan.

Speaking through his trusted translator he said: "Ghana had the strength to beat Nigeria in 2008. My 2010 team has a lot of young players in it and it's definitely going to be a tough match. But we go into the semifinal with confidence after winning our last two games.

"It's always difficult to predict a result. That's why football is such an interesting game, but we'll do everything we can to win."

Ghana are four time winners of the competition but their last win dates back to 1982.

Gyan, Annan, and most of the rest of the squad were in high spirits at an early morning training session at the Angolan capital's Coqueires Stadium.

One player who was missing was skipper and team goalkeeper Richard Kingson who had the morning off. Nigeria set up a date with Ghana with a 5-4 penalty shoot out win over Zambia after a goalless stalemate in their quarter-final in Lubango on Monday.
