The main deadline-day deals
Deadline-day sales were led by Nigeria striker Ighalo, 27, moving to Chinese Super League club Changchun Yatai.
Burnley were one of the busier sides, recruiting 25-year-old Republic of Ireland international Brady from Norwich for a club-record fee having earlier snapped up another midfielder, Ashley Westwood, from Aston Villa.
Southampton bolstered their attacking options by bringing in Gabbiadini, 25, while Crystal Palace secured Liverpool centre-back Mamadou Sakho on loan and signed Serbia midfielder Luka Milivojevic from Greek side Olympiakos.
Swansea City signed Aston Villa forward Jordan Ayew in a swap deal that saw Wales defender Neil Taylor go the other way.
Several mooted moves did not go through on a relatively low-key day, with Celtic keeper Craig Gordon and striker Moussa Dembele staying with the Scottish champions despite reported interest from Chelsea.
Sunderland, thwarted in their attempts to sign forward Leonardo Ulloa from Premier League champions Leicester City, had a bid of about £12m rejected by Southampton for forward Jay Rodriguez.
