Brighton had the highest net spend in the Premier League – £153.6m from an outlay of £195.7m.
They paid a club record £39.9m for Leeds’ Georginio Rutter, £29.9m for Newcastle’s Yankuba Minteh, and more than £25m for each of Ferdi Kadioglu, Brajan Gruda, Mats Wieffer and Ibrahim Osman.
Selling Billy Gilmour for £12m on deadline day, as well as Denis Undav for £22m earlier in the window, brought some money in.
Newly promoted Ipswich had the next highest net spend – £107.6m.
Brighton were not the only club to break their transfer record, either.
Bournemouth recruited striker Evanilson for an initial £31.7m, Brentford signed Igor Thiago for £30m and Fulham brought in Arsenal’s Emile Smith-Rowe for an initial £27m.
Aston Villa, Ipswich, Nottingham Forest and Tottenham also broke their records.
