Supersport.com report that Mashaba has instructed his team to get under the skin of their opponents.
Nigeria come into this game under pressure after losing, at home, to Congo and the national team coach wants his players to inflict more pressure on the Super Eagle.
"We are going well in our preparations for this game but we are expecting a very tough game," Mashaba said.
The South Africa trainer then revealed that he has been drilling his charges to get under the skin of the Nigerian players.
"In our last (training) session, we were working on an exercise where we pick up the runners.
"The idea is to deprive people of space.
"If we deny the Nigerian players space, they will get annoyed and this is what we want.
"If my boys can do that, then we will have a chance." said a confident Mashaba.
"I know the Nigerians. They always want to be cruising, playing free flowing football but if we pick them up and deny them spaces, then we will have a chance.
"Nigeria play a very fast game but we will do what they don't expect which is to get the ball into their half with speed and play our game.
"Take the game to them in one on one situations because they don't like that and take them on.
"It will be not be a tactical game. It will be a psychological thing. It will be war," he said.
The match kicks off at 20.00.
