Mwanzia, who joined the Francis Kimanzi coached side on transfer deadline day, started for the bottom placed side in the 0-0 draw at Kericho Green Stadium. Mwanzia was among the three new faces that were given their first match alongside other new arrivals, Victor Ashinga and Ronald Reagan, who joined Mathare United in the June transfer window.
“I am very happy to have played my first match. It has not been easy because I have had to work very hard to reach this point,” Mwanzi told the club's official website.
“I was not impressed by my performance but I hope for a better show next time. My target is to work harder and help my team to win at least by scoring in the next three matches.”
