Liam Rosenior arrived at Chelsea amid a frantic fixture list, overseeing eleven matches in just thirty‑five days, with some games spaced only four days apart. The compressed schedule left very little room for extensive training sessions, prompting Rosenior to adopt a cautious approach: he deliberately avoided wholesale changes to the squad’s tactics and personnel. After a victorious FA Cup tie against Charlton – his first match in charge in January – Rosenior articulated his perspective to the press. He reminded everyone that this was a side that had lifted the Club World Cup merely five months earlier and had captured the UEFA Conference League the previous season.
"These are players who have already tasted success and have been guided by top‑level coaching," he said, underscoring the high standards already embedded in the club. Rosenior also paid tribute to his predecessor, Enzo Maresca, noting that the former head coach had left a solid tactical foundation. The early results seemed to validate that assessment: Chelsea won eight of the first eleven fixtures under Rosenior, with the only defeats coming in the Carabao Cup semi‑final against Arsenal. During that hectic spell, Rosenior introduced subtle tweaks to the team’s style.
He favored a more aggressive, man‑to‑man press than Maresca, but he applied it sparingly, preferring a light‑touch approach that would not overburden players already fatigued by the relentless match calendar. The schedule finally eased after the FA Cup triumph over Hull in February, when an eight‑day interval between games gave the coaching staff a genuine window for preparation. Rosenior seized the opportunity to embed his ideas more fully. "I told the squad on Thursday that it was the first time we’d had a full two‑day tactical lead‑in since I started," he explained before the subsequent league fixture against Burnley at Stamford Bridge.
"We used the day to run through specific scenarios, rest, and then go out and play. Thursday was the first chance to discuss our style, outline what we want to achieve, and actually practise it on the training pitch." He added a universal truth shared by most managers: the more time you have with a group, the greater your ability to imprint your philosophy. Ironically, the opposite seemed to happen at Chelsea.
The longer Rosenior spent training the team, the more their performances slipped. The Burnley game ended in a disappointing 1‑1 draw, and two months later Rosenior was dismissed after a meagre three wins in twelve matches since the Hull victory.
Those three successes had come against lower‑division opponents – Wrexham in the FA Cup and Port Vale in the same competition – rather than against Premier League rivals. When Rosenior left, Chelsea were enduring a historic slump: five straight league defeats without finding the net, a record not seen since 1912. While it would be unfair to place all blame on him, the pattern of deteriorating displays the longer the squad trained together was a stark indictment of his tenure. Following the Burnley stalemate, Chelsea suffered a third loss to Arsenal under Rosenior after the February international break.
Subsequent defeats to Manchester City and Manchester United in April came after uninterrupted mid‑week training periods, suggesting that extra preparation time was not translating into better results. By April, internal tensions were bubbling to the surface.
Midfielder Enzo Fernández had publicly hinted at a move to Real Madrid during the March international window, and full‑back Marc Cucurella openly questioned the decision to dismiss Maresca while he was away with the Spanish national team. These distractions further eroded Rosenior’s authority. On the pitch, his commitment to an aggressive, man‑to‑man pressing system appeared naïve, especially after a humiliating 8‑2 aggregate loss to Paris Saint‑Germain in the Champions League.
Defender Malo Gusto admitted after the 5‑2 first‑leg defeat that the team needed to recognise moments when it was wiser to sit back and contain rather than press relentlessly. Newcastle United exploited the same defensive frailties in the interim, capitalising on confusion over pressing responsibilities to free up full‑back Tino Livramento, who surged forward and set up the winning goal.
"They were playing man‑for‑man, so we knew we could get behind them," Newcastle striker Anthony Gordon remarked after the match. Rosenior defended his approach, branding it a "new way of pressing" and insisting that Chelsea’s press differed from most teams. Yet the results demonstrated why a full‑pitch, high‑intensity press can be a double‑edged sword: a single lapse can unravel the entire structure.
His temperament also drew criticism. A heated outburst at an Arsenal coach who entered Chelsea’s half during a Carabao Cup warm‑up attracted unwanted media attention. The introduction of pre‑match huddles in the centre circle looked gimmicky, and a bizarre moment saw referee Paul Tierney surrounded by players before the Newcastle game kicked off.
Rosenior’s comments about "respecting the ball" were met with ridicule, and Chelsea failed to score in six of seven matches across all competitions after that incident, the sole exception being a 7‑0 FA Cup demolition of League One side Port Vale. After a goalless draw with Brighton, Rosenior claimed he still felt connected to his players, yet the team's "indefensible" performance suggested a widening gap.
It is reasonable for Rosenior to argue that taking over mid‑season at a club as demanding as Chelsea was always a daunting task. He inherited a squad riddled with inconsistencies, a lack of senior leadership, and a recruitment policy that had left the roster thin on experience. A comparison with Manchester United’s interim manager Michael Carrick highlights the contrast.
Carrick has not been burdened with such a congested fixture list, and he has used his training sessions to steadily improve United’s form. While United have climbed to the top of the table since both managers' first games on 17 January, Chelsea have slipped to tenth place, sliding further down under a coach whose time on the training pitch seemed to hinder rather than help the team.
