#1 Manchester City (€878 million)

Sheikh Mansour's takeover of Manchester City in 2008 is perhaps the most crucial factor why the Citizens have established themselves as one of the powerhouses in Europe.
The mad amount of money he has spent over the last few years has elevated the club amongst the very best footballing institutions in world football at the moment.
Manchester City has spent a whopping sum of €878 million, becoming the highest-spending club on player inquisitions. They also boast the most expensive defence of all time.
Say whatever you want, the club has certainly started winning trophies and is a fine argument to the dictum 'Money can't buy everything'; financial wealth been instrumental enough in helping them win silverware.
Manchester City's record signing is the in-form Kevin De Bruyne(€76m), followed by new signing Aymeric Laporte(€65m) and Englishman Raheem Sterling(€62.5m).
