#3 Manchester United (€ 1.008 billion)

Manchester United is one of only three clubs to spend more than a billion euros. Most of this spending has been done since the retirement of Sir Alex Ferguson as the club has struggled to maintain its position among the European elites. They have broken British records and world records for the highest transfer fee in this period.
The Red Devils broke the world record for highest transfer when United paid 89 million pounds to sign Paul Pogba from Juventus. The club's spending seems to lack proper direction and vision as most of the signings in the last few years have proved to be a waste of money.
Manchester United has done well under Ole Gunnar Solskjaer, but losses in last two matches is a reminder that they need more signings. The next summer will be crucial for Manchester United as they need to ensure that they don't repeat the mistakes of the last few transfer windows.
