Gael Clichy says the difference between Arsene Wenger and Pep Guardiola was their support staff.
Clichy played for Wenger at Arsenal before having a short stint at Manchester City with Guardiola.
He told Tivibu Spor: "These are two different generations.
"Arsene had two assistants and a goalkeeping coach, while Guardiola has eight or nine coaches.
"Smaller details are very important right now. You used to win most matches when you had a top player in your squad. It's important for clubs to spend money these days."
