Liam Rosenior has been sacked as Chelsea head coach, ending a tenure that deteriorated sharply in its final weeks. Four consecutive Premier League defeats without scoring, an 8-2 aggregate humiliation at the hands of PSG in the Champions League, and a catastrophic run of one win in his last eight matches all contributed to a situation the club could no longer justify maintaining.
Those with free bet offers might have been considering using them to back Rosenior to be the next Premier League manager sacked. Yet remarkably,
Chelsea’s hierarchy had initially backed Rosenior firmly, with reports suggesting the club intended to hold off any formal review until the summer of 2027 regardless of results. He had signed a contract through to 2032 as part of BlueCo’s long-term project and only taken the job in January, having inherited a squad mid-season. Whether that patience was ever sustainable is a question the final weeks answered conclusively.
Rosenior ended his time at Stamford Bridge with 11 wins, two draws, and 10 defeats from 23 games in all competitions, a win rate of 47.8%. It is worth asking how that stacks up against the managers who came before him.
Thomas Tuchel: 60%
The benchmark for this era of Chelsea football. Tuchel arrived in January 2021 and delivered the club’s second Champions League title within months, becoming an instant hero at Stamford Bridge. Across 100 games as Chelsea boss, he won 60, drew 24, and lost 16, setting a bar that none of his successors have matched.
The now-England national team manager remains the most successful boss of the BlueCo era, although initially hired by Roman Abramovich, and probably the most popular departure too, given the manner in which he was shown the door.
Enzo Maresca: 59.78%
The closest anyone has come to Tuchel’s numbers. Maresca won 55, drew 16, and lost 21 across his tenure, and did so while delivering two major trophies in the Conference League and the Club World Cup.
His departure at the start of 2026 was jarring, particularly given the silverware he had accumulated, and his falling out with the owners left a sour taste. The statistics suggest it was one of the better managerial reigns in recent memory, whatever the circumstances of the ending.
Mauricio Pochettino: 50.98%
Pochettino’s exit was widely considered harsh at the time, and the numbers give some weight to that view. In 51 games, he won 26, drew 11, and lost 14, operating with a squad that was still finding its shape under the new ownership model.
He never got the chance to build on what he had started, and his 50.98% win rate is at least competitive with what followed. Rosenior, at 52% from a smaller sample, is fractionally ahead, though with a much rockier road in recent weeks.
Graham Potter: 38.71%
BlueCo’s first big managerial call, and arguably their worst. Poached from Brighton amid considerable fanfare, Potter lasted just 206 days in west London, winning 12, drawing eight, and losing 11 of his 31 games in charge.
His win rate of 38.71% stands as the lowest of any full managerial appointment in this period, and the comparisons with Rosenior are ones supporters are beginning to make. Both men enjoyed bright starts before form collapsed. Both retained backing from the board long after results suggested it might be misplaced.
Frank Lampard: 9.09%
A category of his own. Lampard’s interim stint in 2023 is one best filed away and forgotten. One win, two draws, and eight defeats across 11 games represented a torrid period, and a win rate of 9.09% tells its own story.
What makes it all the more remarkable is that Lampard is now rebuilding his reputation impressively at Coventry City, and there will be no shortage of Chelsea fans wondering whether the club legend might eventually earn a third crack at the Stamford Bridge dugout under better circumstances.
Where does that leave Rosenior?
At 47.8%, Rosenior sits third from bottom in this group, below both Tuchel and Maresca by a considerable distance, and also narrowly below Pochettino. He ends his tenure above Potter and Lampard, though that is a low bar given the circumstances surrounding both of those appointments.
What makes Rosenior’s case harder to assess is the split in his record. His first 15 games produced a side that was largely competitive, with defeats coming almost exclusively against Arsenal. The final eight games, just one win, no Premier League goals, and five consecutive top-flight defeats representing the club’s worst run since 1912, tell a very different story.
Chelsea have now worked through five managers in the space of four years under the current ownership. The search for the consistency that defined the Tuchel period continues.
