Former Sunderland manager Steve Bruce believes Paolo Di Canio paid the price for an outdated management style after being ousted by the Black Cats on Sunday night.
Di Canio's controversial reign proved a brief one as he parted company with the club after only 13 matches, his exit coming little more than 24 hours after a 3-0 defeat at West Brom left them rooted to the bottom of the table with one point from five games.
It is believed the Italian's strict regime, unpopular with his players, was key to his departure.
Bruce managed Sunderland from 2009 to 2011, taking over after the arrival of current owner Ellis Short, but working under then chairman Niall Quinn.
He believes the club's approach has changed since Quinn left and Short took over as chairman himself.
Short's next task is to find a replacement for the man he appointed in a storm of controversy last year.
Critics rounded on Di Canio's alleged fascist sympathies, prompting the club to make a stout defence of their new manager.
After debates about his political views had died down, Di Canio kept Sunderland in the Barclays Premier League thanks in part to a memorable 3-0 victory over rivals Newcastle at St James' Park, but little else in his regime went right.
Former Sunderland captain Kevin Ball, currently on the club's coaching staff, steps in to lead the team on a short-term basis, with the club saying a permanent replacement for Di Canio will be announced "in due course".
Bookmakers immediately rated former Chelsea and West Brom manager Roberto Di Matteo as favourite, narrowly ahead of Gus Poyet, previously boss at Brighton.
The new man will face considerable challenges early in his tenure.
Sunderland recruited 14 new players during the summer transfer window, several for the first-team squad but others for the development ranks, but the new-look group is yet to gel.
Just as important as those who arrived were those who left.
Having already lost loan signing Danny Rose following his return to Tottenham, they sold goalkeeper Simon Mignolet to Liverpool and, on deadline day, Stephane Sessegnon to West Brom. It meant they had lost arguably three of their most effective players.
Liverpool, Manchester United and Swansea are next up in the league, offering little hope of an immediate turnaround in fortunes.
