Episodes of the Premier League Years, the Sky Sports show that boils down each season into two hours and is arguably the UK’s greatest cultural achievement, often begin with a montage of that season’s new arrivals.Whoever is putting together the 2026-27 edition might want to start work now, because it could take a while.From the start of this season, nine of the 20 Premier League clubs will have new managers. That’s the highest number in the division’s history: the next highest was eight, which came in the summer of 2016, when Pep Guardiola arrived at Manchester City, Antonio Conte took over at Chelsea and Jose Mourinho signed up for the Manchester United job.But there are even more layers this year. Two of the remaining 11 managers, Michael Carrick and Roberto De Zerbi, weren’t in charge of Manchester United and Tottenham Hotspur at the turn of the year. Ipswich Town, who have replaced Kieran McKenna with Gary O’Neil, will be the first promoted club since Hull City in 2016-17 to enter the Premier League with a different manager from the one who took them up.Mikel Arteta and Unai Emery are the only managers who have been at their clubs for longer than three years. Regis Le Bris, who arrived at Sunderland in 2024, is the fourth longest-serving manager in the Premier League. David Moyes, whose second spell at Everton is barely 18 months old, is seventh. Bournemouth’s Marco Rose is 12th, and he has yet to take charge of a game.Compare this to the start of last season, when the only managerial changes were Thomas Frank moving from Brentford to Tottenham Hotspur and his former side replacing him from within, appointing Keith Andrews. It didn’t take long for the chaos to begin, but 12 months ago, the outlook was steadier.This is a season of unprecedented uncertainty, and what makes it particularly interesting is how much change there has been at the top.Five of the ‘Big Six’ — Chelsea, Liverpool, Manchester City, Manchester United and Tottenham Hotspur — have installed a new manager since the turn of the year. Xabi Alonso (Chelsea), Andoni Iraola (Liverpool) and Enzo Maresca (Manchester City) arrived this summer, while De Zerbi arrived in April and Carrick took the United job on a temporary basis in January, made permanent in May.Throw in Newcastle bringing in Matthias Jaissle to replace Eddie Howe, and of the seven teams that have qualified for the Champions League in the last decade, 85 per cent of them have a brand-new or relatively new manager.
