Kenya midfielder Francis Kahata has conceded defender Joash Onyango keeps on growing as a player because he has no time for casual mistakes and puts up a consistent shift for Simba SC.
The 28-year-old joined Wekundu wa Msimbazi from Gor Mahia at the beginning of the season and has since been one of the key players at the club.
On Tuesday at the Benjamin Mkapa Stadium in the Caf Champions League the defender, commonly referred to as 'the Berlin Wall', partnered Ivorian Pascal Wawa and kept a clean sheet in the 1-0 win over the defending champions, with Mozambican Luis Miquissone scoring the lone goal.
