At least England coach Gary Neville can call upon some form of experience when he rocks up at Valencia.
Unlike Attlio Lombardo at Crystal Palace, a man with zero experience but a fan favourite at Selhurst Park, who was given the player/manager job in 1998.
Even the Italian was shocked by incoming chairman Mark Goldberg's decision.
"I came home last night and received a phone call and was summoned by [Goldberg] and I was proposed the job there and then," he said at the time.
"I had half-an-hour to make a decision and it felt like being run over by a lorry."
Lombardo had only joined as a player from Juventus a year earlier and was assisted in his new role by team-mate Tomas Brolin, who was said to have also acted as interpreter due to the boss' lack of English.
Palace were relegated at the end of the season, Brolin left but Lombardo stayed on as a player under Terry Venables and eventually said goodbye in 1999 when he joined Lazio.
