4) Manuel Pellegrini
Manuel Pellegrini, the current coach of West Ham has quite the resume to his name. He has won the national leagues in 4 different countries with the Premier League title with Manchester City being his most prestigious one. The Chilean is the only non-European manager to ever win the Premier League.
Having managed financial powerhouses such as Real Madrid and Manchester City in the past, it is no surprise that Pellegrini is so high up in this list. He has spent 1.1 billion euros on 82 players so far.
Pellegrini was the manager in charge when Real Madrid brought Cristiano Ronaldo, Kaka and Karim Benzema to Real Madrid from Manchester United, AC Milan and Lyon.
He was also responsible for the signing of Kevin De Bruyne, Raheem Sterling and Fernandinho to Manchester City from Wolfsburg, Liverpool and Shakhtar.
3) Pep Guardiola
From an ex Manchester City manager to a current. Pep Guardiola is no.3 in the top 10 highest spending managers in the history of football. Pep’s history of trophies with Barcelona, Bayern Munich and now Manchester City have led many to proclaim him as the greatest manager in the game.
He won 14 trophies at Barcelona which included a treble and a double, both in combination with the Champions League. He then won 7 further trophies at Bavaria, picking up the Bundesliga in all his 3 seasons. With Manchester he has also won 7 more including an unprecedented domestic treble last season.
His success hasn’t come cheap though as Guardiola has spent 1.2 billion euros on 52 players; the lowest signings in the list, just a shade over half of what Wenger purchased.
His most notable signings include Aymeric Laporte, Bernardo Silva, David Villa, Cesc Fabregas, Douglas Costa, Dani Alves and Javier Mascherano for his champion sides from the past and present.
