Ghana coach Milovan Rajevac has backed Kevin-Prince Boateng to retain his focus ahead of the crunch World Cup clash with Germany on Wednesday.
The Black Stars go into the Soccer City contest topping Group D but need to beat their illustrious opponents to be guaranteed of progression into the last 16.
The clash has been given added spice after Portsmouth midfielder Boateng became public enemy number one in Germany, the country of his birth, following his tackle on Michael Ballack in the FA Cup final ruled the German skipper out of the World Cup.
Boateng could also come up against his half-brother Jerome, a Germany international who has reportedly broken off contact with him over the Ballack incident, but Rajevac believes his player will cope.
The Serbia boss said: "We have talked about this, the media created this problem. Even if there had been a problem it lies behind us.
"Kevin-Prince Boateng will do his best, he will focus, he will not be provoked, he is a professional. They may be brothers off the pitch but on the pitch they are not brothers.
"He will do his best and play without any pressure and play his normal game in order to reach a good result."
Rajevac expects his team to be well supported by their own fans and also by neutral South Africans keen to see at least one side from the continent make it into the knockout phase.
He added: "Of course we are playing in South Africa and we are the only African team with a realistic chance of the last 16 so that will give us extra motivation to play an excellent game against Germany.
"This is the only way to win against very good players."
