Ghana international Harrison Afful believes that Esperance are capable of going past Barcelona and other top sides at the Club World Cup in Japan.
Esperance, the African champions must first beat Qatar's Al Sadd in their quarter-final at the weekend before a possible clash with the European champions in Yokohama on December 15.
Afful, who scored the decisive goal to win the CAF Champions League for Esperance last month, said the team feared no one.
"Nothing is impossible. I keep on watching my goal over and over again on my computer," said the Ghanaian full-back as he recalled his screamer against Wydad Casablanca.
"I can hardly recognise myself because I'm not used to scoring goals. I'm more of a provider.
"I never get tired of watching my team mates congratulate me and hearing the Tunisian commentator go wild," he told fifa.com.
Though Al Sadd are likely to provide stubborn opposition in the quarter-finals Afful believes Esperance could go far in Japan.
"We want to go to Japan and put in some good performances," said the 25-year-old, whose goal made Esperance kings of Africa for a second time, 17 years on from their first triumph.
"It won't be easy for us, but with the ability we've got, I can tell you, we're capable of going a long way in this competition."
