Welcome to The Debrief, Sky Sports' weekly column where Adam Bate mixes statistics with personal insight to dissect the most compelling narratives emerging from the latest Premier League fixtures. This edition focuses on the recent turmoil surrounding Chelsea and the broader implications for other clubs. Earlier this month, former manager Liam Rosenior reminded everyone that, despite the endless chatter about his tenure, his side had once sat fourth in the league table after he took charge. Unfortunately, that snapshot is now a distant memory; Chelsea have slipped to ninth place under his stewardship, a stark contrast to the early promise he highlighted.

The latest 2-1 defeat to Manchester United marked the club's fourth consecutive loss, three of which have come at Stamford Bridge. This run echoes a previous spell of three straight defeats at home, a period that even featured a loss to Oldham when Tony Cascarino was leading the line for the Blues. The pattern suggests that the club is navigating a particularly unsettled phase, and Rosenior's usual optimism is beginning to look fragile.

Supporters have grown accustomed to Rosenior’s vigorous defence of his record, often insisting that the loss to United was undeserved. He argued, "They had a single chance on our goal when we were reduced to ten men after an injury, and then we faced wave after wave of attacks, countless crosses into the box, and moments we simply failed to capitalise on. We struck the woodwork four or five times." He added, "I won’t lie – I can’t comment on things I haven’t witnessed. I saw a team that dominated from the first whistle to the last, but we need to manage those moments better.

That’s what’s costing us points right now." There is some truth to Rosenior’s assessment. Opta data indicates that only three of Chelsea’s attempts actually hit the frame, underscoring a shocking lack of clinical finishing. Since mid‑March, Chelsea have been the only Premier League side that has failed to find the net despite registering the highest number of shots.

This paradox – a team that creates chances but cannot convert them – is a statistical outlier worth examining. United, in contrast, enjoyed the clearer opening in the match.

While Chelsea’s volume of opportunities was impressive, the quality of those chances was comparatively low, a recurring theme throughout Rosenior’s recent tenure. In fact, over the past ten games only Wolverhampton Wanderers have posted a lower expected‑goals‑per‑shot ratio than Chelsea, highlighting a deeper issue with how the Blues are penetrating the final third. The problem may extend beyond tactics to personnel.

It is unlikely to be mere coincidence that United’s Matheus Cunha delivered the decisive finish. The Brazilian has consistently outperformed his expected‑goals metric in the Premier League, while every Chelsea attacker on the pitch Saturday has, over the course of their Premier League careers, under‑delivered relative to their xG expectations.

Football often hinges on fine margins, and it would be unwise to write off Chelsea’s chances forever. Yet when contemporaries such as Erling Haaland and Mohamed Salah were the decisive factors for their teams, the narrative of Chelsea’s “bad luck” in front of goal appears to be more than just a streak of misfortune – it may be embedded in the club’s current playing model.

Switching focus, Jamie Carragher recently analysed Liverpool’s rising star Florian Wirtz ahead of the Merseyside derby. Carragher praised Wirtz’s statistical output – four goals and three assists – describing it as "neat and tidy" and noting that the player’s contributions were significant despite not always translating into clear-cut scoring opportunities. He highlighted the quality of the Anfield pitch and suggested that Wirtz should be dominating games, yet Liverpool only secured a late win through Virgil van Dijk, while Wirtz’s impact remained limited.

Post‑match data illuminated why the £116 million Bayer Leverkusen acquisition has been difficult to evaluate. Wirtz currently ranks second in the league for open‑play chances created, trailing only Bruno Fernandes. However, a closer look reveals that many of those chances were either half‑chances or poorly executed.

One involved a clever back‑pass to Cody Gakpo that fizzled, another saw a neat ball into Alexander Isak’s path that resulted in a simple save. The remaining two were speculative passes leading to low‑probability shots.

The eye test tells a different story. Wirtz struggled to retain possession in a fast‑paced match, often being out‑muscled and failing to impose his presence as many fans expected. He managed just one successful dribble and no shots on target. While his work rate is undeniable – he ranks fourth in the league for total runs this season – the quality of those runs often lacks the decisive edge required at the highest level.

Critics point out that Wirtz has yet to display the swagger and risk‑taking seen in players like Rayan Cherki at Manchester City. Though he was a leader at Leverkusen, he has not yet assumed a similar role at Liverpool.

His long‑term contract offers some leeway, but patience is not infinite. Carragher summed it up: "He is in a new league, new manager, new system, but we are ten months in now. We need to see a lot more." Turning to the north, Newcastle United continue to showcase the high‑intensity style that has defined Eddie Howe’s tenure.

They rank second in the league for sprints and have consistently been among the top five in that metric across all five of Howe’s seasons. However, this relentless pressing has begun to expose defensive vulnerabilities.

When Newcastle’s press slows or the back line fails to push up, gaps appear. This was evident in their 2-1 loss to Bournemouth, a match where they never truly controlled the tempo. Howe maintained that the margins were fine, yet Andoni Iraola’s side generated superior chances, reflected in an expected‑goals total of 2.99 – the highest Newcastle have conceded this season, edging out the previous week’s tally against Crystal Palace.

Since the end of January, Newcastle’s expected goals against have been worse than every other Premier League side except bottom‑placed Wolves. They sit sandwiched between three clubs fighting relegation, confirming that their defence is now one of the leakiest in the competition. Their home record is particularly alarming: five defeats in their last six league games at St James’ Park, matching the total number of losses they endured throughout the entire previous season. The once‑formidable fortress now feels porous, and this erosion of home advantage places additional pressure on Howe.

A struggling Newcastle inevitably reflects on its manager. Even the often‑criticised Steve Bruce never saw his side dip as low as Newcastle’s current league position.

Consequently, Howe’s selection choices and recruitment strategy are under intense scrutiny. Players such as Yoane Wissa have made minimal impact, Anthony Elanga has been inconsistent, and Nick Woltemade has become a problem that needs solving. In summary, both Chelsea and Newcastle illustrate how statistical dominance does not automatically translate into results.

Whether it is a lack of clinical finishing, tactical rigidity, or defensive frailties, the Premier League continues to reward teams that can convert chances and maintain solidity at the back. The coming weeks will be crucial for Rosenior, Howe and their respective squads as they attempt to reverse their fortunes before the season draws to a close.
