Who are the three team managers that hold the record for the most appearances in the FIFA Club World Cup final?

Context: Pep Guardiola and Carlo Ancelotti are the only managers to have won three FIFA Club World Cups; Guardiola won twice with Barcelona and once with Bayern Munich, while Ancelotti was victorious once with Milan and twice with Real Madrid. Rafael Benítez, alongside Ancelotti and Guardiola, holds the record for the most appearances in the final, leading English clubs Liverpool and Chelsea, as well as Italian club Internazionale, to one final each. Lamine N'Diaye of Senegal in 2010, Faouzi Benzarti of Tunisia in 2013 and Masatada Ishii of Japan in 2016 were the only non-European and non-South American managers to have appeared in the final. The aforementioned three managers, as well as Zoran Mamić in 2018, Ricardo Ferretti in 2020 and Ramón Díaz in 2022, are the only ones to have led a club outside Europe and South America into the decisive match.

Answer: Rafael Benítez, Pep Guardiola, and Carlo Ancelotti hold the record for most appearances.
