Zola says he also had the chance to leave Chelsea after his first year - and has no regrets turning the offer down.
“I am sure those players value the club but at the same time, when the call comes from clubs like Barcelona, Real Madrid, you pay attention. Maybe you don't go but you pay attention," he told The Sun.
“They would be leaving a special club, in a special league, in a special place.
“After my first year at Chelsea I was offered the chance to go to another club.
“But it was 'thanks but no thanks'. I had the feeling I was in the right place, even though I could have earned more money by leaving.
“We have to be honest — money is an important factor.
“As a footballer it is like you run a company and you have to think to do the best for your company — your family.
“In normal business if you are offered a better job with more money, 90 per cent you will go.
“For me, money was not the main thing but that is only me."
