I speak to the Spanish players that we have in Spanish.
Liverpool is one of the great institutions of the world, and you understand that when you see it from the outside, but you only really get to know when you go inside as manager.
Sometimes keepers are looked at differently to outfield players.
I think wherever you go, you have to go to win.
I'm enriched by all my experiences, good and bad, but I've always tried to remain committed in my life as a coach and always positive.
I think all you can worry is that you make the team the very best they can be.
You can go to Old Trafford as Liverpool manager and get a draw, and it's not a bad result. At Celtic, there's an expectancy to win home and away.
The biggest thing you can have as a football manager is happiness and energy.
I know how quickly it can all change. I nearly won the title at Liverpool, and everybody's saying, 'Sign him up' - then, very quickly, I was out.
As a guy from Northern Ireland who supported Celtic and worked in football, I'm living my dream here.
All my career I have done that, worked with talents, improving 19-year-olds, 20-year-olds, 17-year-olds, 18-year-olds.
I love my work.
When I went in to Liverpool, my job in the first season was to cut the budget. You only need to look at the players who left. Maxi Rodriguez, Alberto Aquilani, Pepe Reina.
I always felt that by the time I would leave Chelsea I was ready to be a number one. I'd had a long apprenticeship so when I was to go, it would to be a No. 1.
I've always been inspired by people who can speak other languages.
Don't be afraid to make mistakes and be able to laugh at yourself.
I always think if you speak to someone in their second language, you speak to their head. If you speak in their first, you speak to their heart. I've always tried to let players see that.
Football's a global game.
The only thing that Celtic doesn't have is the propaganda, which is the Premier League. In every other aspect of football, Celtic is a huge club: fan base, stadium and history. They have a fantastic history. What it doesn't have is the opportunity to play in the Premier League.
It was important for me, when I left a club like Liverpool, to one, have a breather, but then my next job, I needed pressure. And there's a pressure at Celtic. It's a huge club; there's an expectancy to win every game.
