"Truth be told, any football game now is gonna be tough, all football matches played now is all about who wants it more," Kerr tells KickOff.com.
"It's all about do you want to be in the PSL for 2019/20. Do you want to be playing with the giants of South African football? So it's all about character. Tomorrow it's the start of a very, very tough week for us.
"But we will only concentrate on the Polokwane game, and once it's finished we will start concentrating on the other two. Winning will make it easy to go to Orlando to play a team that's trying to win the PSL. Losing will give hope to the teams below us, and that's something we can't afford to do.
"We have to get into this game now ready to fight, ready to showcase our true character in how we will approach every single game now and in the future.
"I know what my players can do, I know what they can play like. I just wanna make sure that they do what they need to do every single day. The game against Polokwane is not gonna be easy, nobody has a right to win the game, it's entirely up to the players on the day whether they perform up to their ability, or Polokwane do better than us.
"Everybody is fit and available for selection, I've got a good headache, 30 players, 28 players to select the starting eleven positions and on the bench, so it's a good problem I have."
