The two sides meet in the Kenyan Premier League top 8, Wednesday 4 April 2012.
Nandwa was recently appointed to the position, with the main task spearheading the return of the club to the top of the Kenyan Premier League standings.
That though will come another day, with Tusker first on the agenda in the knockout tourney, where Nandwa is hoping for an upset.
-It is a tough game. They are a big team and have good players.
-Over the weekend, we had a good result at a tough place to go to, so the confidence is better. However, this is a knockout competition where anything can happen and the match can go anyway.
-We have a good team with confidence and a great chance of going through, Nandwa told Futaa.com.
Rangers will be hoping to join SoNy Sugar and Ulinzi Stars in the semi finals of the tourney.
