I'm still very professional about my fitness. I stay in trim as I always did.
I prefer more spicy food to your Italian to be fair.
I played for 30 years, 20 with England and I did it by setting goals.
As a goalkeeper you need to be good at organising the people in front of you and motivating them. You need to see what's going on and react to the threats. Just like a good manager in business.
