Jose Mourinho has become the first manager in football history, to take his career transfer spending past £1billion.
The Manchester United manager, passed that landmark during the current window, when he signed Romelu Lukaku for £75million from Everton.
A breakdown of Mourinho’s all-time spending, shows he has now spent just over £1.1bn in 17 years as a boss.
His nemesis in Spain and current cross-city rival in Manchester, Pep Guardiola, has spent £859m, in a little over half the time.
Mourinho and Guardiola are both considered among the all-time great managers, although both have had massive resources to play with for much of their managerial careers.
The only other manager who comes close to their spending is Bayern Munich manager Carlo Ancelotti, with Chelsea one of nine clubs he has managed in 22 years, spending £970m gross to date.
