Milovan Rajevac insists he still has enough time to work with his Ghana players after only just now meeting with most of his 30-man squad in Paris.

Twenty members of the team left Accra on Sunday evening for their French base camp and will be joined by the remaining 10 European-based players - including Chelsea's Michael Essien, John Mensah of Lyon, Kevin-Prince Boateng from Portsmouth and Inter Milan's Champions League winner, Sulley Muntari.

There have been questions raised before the departure that the camp may be too short, but Serb Rajevac insists otherwise. "We would have to be patient and see as we start our work," he told the Ghana Football Association (GFA) website. "We have had more days to assemble and there will be enough time to work with the players.

"All [players] will get the chance during the warm-up games. We would try some things and give opportunities to all. It's important to try some options and check on the every detail," he said.

Players like Stephen Appiah, John Mensah and Michael Essien are crucial to the plans of the team, and their fitness will spur the team on.

Ghana's Derek Boateng on the fitness of key players

Meanwhile, midfielder Derek Boateng has played down the injury problems that have hit the team. Doubt still remains over the fitness of Essien and Mensah, while the likes of Stephen Appiah, John Paintsil and Laryea Kingston have only just returned from injury.

"Key players like John Mensah and Michael Essien are battling injuries but I'm convinced they will recover ahead of time," the Getafe midfielder Boateng told CAF's website. "Their experience is critical and we need them to realise our ambitions. The infusion of some young players is a positive sign for the team. They have demonstrated that they can be relied up and that's one of the strong points of the team.

"If we have all our players fit, then we can talk about the ultimate. Players like Stephen Appiah, John Mensah and Michael Essien are crucial to the plans of the team, and their fitness will spur the team on. For now, our immediate target is to advance past the group stage and the rest will follow," he said.

The Black Stars, who are making a second appearance at the FIFA World Cup™ following their debut four years ago, are in Group D for the finals, alongside Germany, Serbia and Australia. They play two friendly games against the Netherlands in Rotterdam on 1 June and against Latvia in Milton Keynes on 5 June, before flying out to South Africa a day later.
