The summer transfer window was the richest in Premier League history as total spending for the calendar year reached £1bn for the first time.

Summer outlay passed £870m, 4% up on the record set last year.

The biggest spenders, Manchester City, paid the two biggest fees, £55m for Kevin De Bruyne from Wolfsburg and £49m for Raheem Sterling from Liverpool.

Manchester United's £36m signing of Monaco teenager Anthony Martial was the biggest deadline-day move.

That fee could rise to £58m with a number of incentive-based add-ons.

Manchester City broke their club record twice this summer to bring De Bruyne and Sterling to Etihad Stadium as they became England's highest gross spenders in a single window.

Their total spend of approximately £160m beat the near £150m outlay of Manchester United in summer 2014, including deals for Fabian Delph, Patrick Roberts and Nicolas Otamendi.

The Premier League leaders were boosted this summer by having restrictions on their transfer spending lifted after meeting their Financial Fair Play target.

City's spending in 2014 was capped at £49m and they were also fined £16.3m for breaching Uefa rules.

The four Premier League clubs competing in this season's Champions League - City, United, Chelsea and Arsenal - had a combined gross transfer spend of around £340m, representing around 40% of the aggregate gross transfer spend by Premier League clubs.
