Transfer window: The 2013 summer in numbers

The four Premier League clubs competing in this season’s Champions League - Arsenal, Chelsea, Manchester City and Manchester United - had a combined gross transfer spend of £230M in the summer transfer window, representing 37% of the aggregate gross transfer spend by Premier League clubs.

Arsenal signaled their intent to spend big and they did, eventually, with the £42.4M signing of Mesut Ozil from Real Madrid on transfer deadline day - the single biggest amount spent by a Premier League club on a player.

Manchester United also left it very late, with their their £27.5mMcapture of Marouane Fellaini on deadline day falling just short of the £30.75M they paid Tottenham for Dimitar Berbatov in September 2008.

Chelsea did not make any major signings on the final day, but they had already sealed deals for midfielder Willian from Anzhi Makhachkala for £30M and Germany midfielder Andre Schurrle for £18M.

The London club remain top of the spending tree for the last 10 years, having laid out £623M in the summer windows and £135M in the January windows - a combined figure of £758M.

Manchester City are second on the list of transfer spending 2003-2013 (£700M), with Liverpool third (£482M) and Tottenham fourth (£477M)

In fact, it was Tottenham and Manchester City who spent the most this summer, their combined total in the region of £200M, although Spurs will have recouped much of what they have spent through the £85m sale of Gareth Bale to Real Madrid.
