Former Harambee Stars coach Dennis Oliech says being a stammerer affected his social life while growing up.
Speaking in Churchill’s The Journey Series he said he was mostly quiet as he did not know how people would react.
"I am shy and I stammer and it has really affected me," he said.
"I had to learn to tame it as I had to do interviews, I was very shy in class because I would fear what people would say.
"I had such a challenge because I was a good footballer and I was also the captain so I had to step up."
He said over the years he managed to control it a bit.
Oliech has played for various teams, among them Mathare United.
"While in Form 2 is when I started playing for Mathare United, I would be paid 18K," he said.
"At the time my dad had passed away and so my mum had to take care of nine kids.
We had a hotel and that really helped as we never slept hungrily, it also helped us not to join crime.
"Most of our neighbours were killed as they would go steal in order to feed their families."
