@Nick KaufmanAlso, I want to say that I find manager changes overrated and ineffectual.
It's like Japanese kabuki, in which a team fires a manager as someone who has failed to deliver results commensurate with expectations, only to turn around and seek salvation among a manager pool that 99.99% consists of managers who have been fired for having failed to deliver results commensurate with expectations.
Reading the Everton thread, I got to thinking about what managers are out of work and possible options for the Toffees. And I also thought it might be fun to have a thread for general managers/coaching staffs/DoFs and tactics as others see fit/interesting. We can always let it lie fallow if these discussions are more fun to have when they're specific to an opening.
Just perusing Transfermarkt, a few names of unemployed managers jump out (last club in parentheses): Ernesto Valverde (Barcelona); Ole Gunnar Solkjaer (Man U); Nuno Espirito Santo (Spurs); Frank Lampard (Chelsea); Jogie Low (Germany NT); Pirlo (Juve); Koeman (Barca); Favre (Dortmund); Gattuso (Napoli); Jesse Marsh (Leipzig); Fonseca (Roma); Niko Kovac (Monaco); Klinsmann (Hertha Berlin); Celades (Valencia): Rudi Garcia (Lyon); Villas-Boas (Marseille); and of course now Rafa Benitez (Everton).
I know a lot more about some (Valverde, Ole, Nuno, Koeman, Low, etc.) than others (Kovac, Garcia, etc.), but I think this is an eclectic group overall as one would expect. You have lots of older managers who are well-traveled as well as some recently retired legends--a trend that has seemingly picked up a lot of steam recently.
To provide some more details regarding the ones I know more, let me start by discussing Ernie Valverde. Ernie was sacked in January 2020 after a successful but ultimately frustrating stint at Barca for 2.5 seasons. He won La Liga in his first 2 seasons, and the team was second in the table when he was let go. He also won the Copa del Rey in his first season, and lost in the final in his second full season. However, he will ultimately be remembered by most as the manager during the Roma and Liverpool UCL debacles. I note that Lucho was in charge for the Atleti and Juve UCL exits the years following the win over Juve in '14-'15, and the Vilanova-Martino years after Pep also involved exits to Bayern and Atleti respectively. He was succeeded by Quique Setien who basically presided over the true collapse of Barca's footballing status. So in retrospect, I think most Culers view Ernie's reign as one where he was a players' manager, a professional, and tactically astute, but either stubborn or boxed in with respect to squad selection (minimal rotation and key players were running on fumes) and not willing or able to offer aesthetically pleasing football. Ernie has a long career of first division manager experience that began with Bilbao back in 2002 (2 seasons), Espanyol (2 seasons), Olympiakos (1 season), Villareal (1 season), Olympiakos (2 seasons), Valencia (1/2 season), and Bilbao (4 seasons) before going to Barca. He seems mostly at home in Spain and I have no idea if he speaks much English, but I think he's a very high quality manager that can manage a club successfully.
