Premier League clubs spent more than £155m on transfer deadline day as the summer window outlay reached a record £1.165bn.
Teams had already spent a combined £1.005bn as of 08:30 BST on Wednesday, shattering last year’s record £870m.
Thirteen top-flight teams broke their own transfer records.
The 20 clubs in the Premier League have benefited from a record £5.1bn television deal which came into effect this season.
“As has been the case for a number of years now, the increases in broadcast revenue, with the 2016-17 season being the first of the new broadcast deal cycle, is the principal driver of this spending power,” said Dan Jones, a partner at financial analysts Deloitte.
Not only did this year’s figure of £1.165bn break the record set this time last year, but it also dwarfed the £215m spent during the first window in the 2003-04 campaign.
Such financial strength owes much to the record £5.136bn domestic TV deal, which was more than £2bn larger than the previous contract, which ran from 2013 to 2016.
