Christopher Katongo feels the pressure the Bafana Bafana players will be under to impress Gordon Igesund might play to Zambia's advantage when they clash in the Nelson Mandela Challenge.Chipolopolo are in town to face South Africa at the FNB Stadium on Wednesday, and skipper Katongo believes that Igesund's players have a lot to prove to their coach ahead of the 2013 Africa Cup of Nations.Katongo explained to Football411: "It is a new team with Pitso (Mosimane) gone and all these players want to prove themselves to the coach so they can have a place in the AFCON squad."So it is not gonna be easy for them, but as for us we have the same players and nothing has been changed so we know each other. We don't have pressure," he added.Kick-off for Wednesday's clash is 20:00 at Soccer City in Johannesburg.
