Louis van Gaal splashed out a total of €200 million on seven players, including a British-record fee for Angel Di Maria, as 2014 saw a huge increase in clubs' outlays
The huge numbers were led by Manchester United, whose huge outlay of €200 million on seven players was the highest single-window spend yet by a British club.
It included a €75m deal to recruit winger Angel Di Maria from Real Madrid, the highest fee ever spent by any British team, and a late loan deal for Monaco's Radamel Falcao.
The Colombia international sealed a sensational switch to Old Trafford after a long summer of intense interest from the likes of Carlo Ancelotti's Champions League winners and Premier League holders Manchester City.
According to analysis from Deloitte’s Sports Business Group, summer spending is up by almost €250m on 2013's total of €796m, which was at the time €164m higher than ever before.
"This summer transfer window is one of records," said Dan Jones, a partner in the Sports Business Group.
"There are a number of factors contributing to this summer's spend, including the showcase for global talent a World Cup provides. However, one of the main drivers of Premier League spending continues to be the increased resources clubs now have as a result of improved broadcast deals.
"Last season the average Premier League club received around €31.6m more in central broadcast distributions than they did in 2012-13, which helped fuel a record transfer window last summer. We are again seeing Premier League clubs use these resources to contribute to what is a new record this summer."
