Jose Peseiro defended his record in club management at his first media conference on Sunday, after being unveiled as the new coach of Egyptian giants Al Ahly.
The 55-year-old Portuguese, formerly in charge of the Saudi Arabia national team, replaces Fathi Mabrouk but has met with some fan resistance over an allegedly poor record.
"I do not understand why you doubt my ability to coach Al Ahly. Do you know the names I've trained before?" he asked reporters in Cairo on Sunday.
"I've worked with Zinedine Zidane, Luis Figo, Roberto Carlos. Do you think I can't handle Ahly?" Peseiro said.
Peseiro was assistant coach at Real Madrid for the 2003-2004 season before embarking on a head coach career at clubs such as Sporting Lisbon, Panathinaikos, Rapid Bucharest and Sporting Braga.
He was most recently sacked by Al Wahda of the United Arab Emirates in February.
No details have been given of Peseiro's contract terms with Ahly who are African football's most successful club with a record eight African Champions League triumphs and 11 other continental titles.
Mabrouk was sacked after the club lost in the semi-finals of the African Confederation Cup to South Africa's Orlando Pirates this month.
