Munyua, who had never previously left Africa and took a break from his job as a veterinarian in Kenya to compete at Alexandra Palace, produced the shock of the Championship by defeating 18th seed Mike De Decker in the opening round.

It resulted in the President of Kenya, William Samoei Ruto, congratulating Munyua on his sensational victory.

The 30-year-old had unanimous support from the Ally Pally crowd in his second-round match against Kevin Doets, but he was unable to defy the odds for a second time and was beaten 3-0 by the world No.38.

Yet after one life-changing experience came another for Munyua, who on Saturday was invited to watch Chelsea, the club he has supported as a boy, at Stamford Bridge.

And we spoke to the man whose nickname is aptly 'Why Not?' about his whirlwind fortnight and his long-standing love of the Blues...

David, welcome to Stamford Bridge. Firstly, has everything you have achieved over the past two weeks sunk in yet?

'I'm just trying to take it all in and enjoy every moment. I know it will take some time for it to sink in because everything I have experienced is for the first time. It is a big deal for me.'

What impact do you think your performance at Ally Pally will have at home in Kenya and potentially beyond?

'I feel things are already changing and people are looking at the sport differently in Kenya. So I think it is a good opportunity to inspire the next generation and help the sport in the future.

'Coming to Ally Pally and performing shows everyone what can be done. There doesn't have to be an excuse. Also, coming here to Stamford Bridge is something inspirational for many people who have a passion for football.'

Do you share that passion?

'I do! When I was growing up at school, I used to play a lot of sports, including football. That meant that I met a lot of different people and players and got to go to a lot of different places.

'I always enjoyed that because the different people you meet and the different cultures you experience strengthen your mind. So I feel that sport for me has always done this.'

And when did Chelsea come into your life?

'It was during the time of Didier Drogba at Chelsea that I was a young boy and I always used to play football. We were doing our thing and I just knew that this was the club I needed to support. That proved a nice choice as the major trophies, we have them all!

'I remember watching the 2012 Champions League and so many people were going crazy when we won. Everyone was so happy. There are so many memories like this, even the Club World Cup this year. That one was great as I don't think many people expected us to win it, but we did!

'This is why Chelsea has been an inspiration to me in my career because when people do not expect us to do something or win a trophy, we find a way to do it.'

You've mentioned Didier Drogba, and several other legends of African football have called Chelsea home down the years...

'We have that history and I think this is important; it inspires people and shows them that if these players did this, then they can too. That is a great thing for football and for young players to have people to look up to. They have proof that it can happen with the talent and the effort.'

Now you are someone who can inspire people...

'That feels great for me. People can look at me and say, 'Okay, life hasn't always been so smooth, but he never gave up and look where he is now.' That is something special for me.'

What does it mean to you to visit to Stamford Bridge and watch a game live?

'Phenomenal. It is one of the greatest feelings and I will always remember this. Growing up, I always watched the games if I could, and if I couldn't, because I was brought up in a development where we couldn't always access television, I would listen on the radio.

'So being here at the stadium, being by the pitch, it is something I always dreamed about. It is amazing, but it's also not just for me.

'Many of my fans posted asking me to come to Stamford Bridge, as they have always wanted to come here too. So I had to find a way to get to Stamford Bridge and it is very special to be here.'

We know your nickname is 'Why not?', so what comes next for you?

'I'm not the same [after this trip]. I've interacted with different people, had new experiences and had exposure to different things. I know what to work on in my career and I want to try to be better than I was before. In a few months, or maybe a few years, I want to be world champion – like Chelsea!'
