“When I was at Esperance they thought the championship was won every time, but when I went there they had lost the previous one," Cardoso told the media.
"So, to win the championship last year at Esperance was tough because they were not the champions, Etoile du Sahel were the champions because they thought winning it was easy.
"They were just thinking about the Champions League and when you do that you make a big mistake. This championship will be tough, believe me, and we don't think about the Champions League or the [Fifa Club] World Cup. We do our schedule according to what we have to do," added the Portuguese.
"Believe me, yesterday [Friday] I was so pissed off because we had a day to think about the World Cup when we should be thinking about Pirates.
"I was not happy believe me because I know what we have ahead. So for us, ahead is only and always the next match."
