Managerial career In his managerial career, he has been head coach of Egypt, and has been assistant manager of the Netherlands (under Frank Rijkaard and Louis van Gaal) and Ajax (under Ronald Koeman). He became interim manager of Ajax after the resignation of Koeman. He was manager of AC Ajaccio in France Ligue 2 from 2006 to 2007. He returned as manager of Egyptian giants Zamalek in August 2007. He had previously managed them from 1994 to 1999, winning the Egyptian Cup in 1999, the African Cup of Champions Clubs in 1996 and the Afro-Asian Club Championship 1997, the last two being the biggest club level prizes available to CAF clubs. Krol's return to Zamalek was meant to be a stabilizing presence, the club having gone through several managers in the preceding two seasons. His stay however would be a short one. He ended his sole season by winning one Egyptian Cup with Zamalek, within one season he would leave and sign a three-year contract with the South African giants Orlando Pirates. In the three years with the Orlando Pirates he won two South African cups (and a finalist once) and won the national league, all in his last year in charge of the team. Those cups include MTN8 and Nedbank Cup. Despite that success his contract was not renewed. He won the Tunisian championship with CS Sfaxien in 2012–2013, after a fierce battle with the other 3 of the Tunisian big 4. After that success, he was contacted to lead the Tunisian national team in the play off qualifying to the 2014 world cup against Cameroon. He accepted that role and simultaneously became manager of CS Sfaxien and Tunisia in September 2013. He won the 2013 CAF Confederation Cup with Sfaxien. He resigned from his duties as Sfaxien coach after the second leg of the final against TP Mazembe on 30 November 2013. He quit as the national team interim coach following Tunisia's loss in the World Cup play-off. In January 2014, he was appointed new head coach of Tunisian side ES Tunis. Personal life On 6 July 1972, Krol married Yvonne van Ingen. The couple have a daughter. On 26 September 1974, together with teammate Arie Haan, he opened a snack bar on Reguliersbreestraat in Amsterdam.
