If you win the Champions League, you become known across the globe, but the World Cup has always thrown up new stars and developments.

If you want to win the Champions League, you have to have talent, good players, luck in the draw, and, in certain moments, the right referee.

I learned a lot from my father. I'm very lucky to have a father who was a professional athlete.

I am passionate about football. My support for Celtic FC has got me through some hard times in my life. I still play regularly, too.

Some of my friends said I wouldn't have a future in football, as did some of my family, but I still believed in the potential I had. My mum would tell me I needed to get a proper job, but for me, I didn't want to be anything other than a footballer. That led to some tension and frustration between us.
