Milovan Rajevac watches his squad train ahead of Thursday's match Ghana coach Milovan Rajevac says his young squad have "proved" themselves at the Africa Cup of Nations in Angola.

The Black Stars face Nigeria in the semi-finals on Thursday, despite going into the competition missing many key members of the team.

They have improved steadily throughout the tournament and their performance in the quarter-final against the hosts was their best so far.

"I took eight players from the squad who played at the Under-20 [World Cup] and they have proved their quality, they are tough," Rajevac said.

But he acknowledged that the game against the Super Eagles will be their biggest test to date.

"Nigeria is an experienced team and the match will be tough, because it is a semi-final," the coach said.

Ghana against Nigeria is unpredictable - Ghana striker Asamoah Gyan

Rajevac said he thought Nigeria would put in a stronger performance than the one in their quarter-final against Zambia, which they won on penalties after a 0-0 draw.

Meanwhile Ghana star Asamoah Gyan says the players are looking forward to the clash with their west African rivals in Luanda.

And he reminded people that Ghana have had the better of their near neighbours in recent years.

"They don't want us to beat them for the third time in three years," Gyan said.

"We are ready and we're going to do everything possible to win this match and qualify for the final [but in] a derby game, you cannot predict - Ghana against Nigeria is unpredictable."
