Welcome to The Debrief, Sky Sports' weekly column where Adam Bate mixes statistics with opinion to dissect the most compelling narratives emerging from the latest Premier League fixtures. This edition focuses on the recent turmoil surrounding Chelsea and offers a broader look at the challenges faced by Newcastle United under Eddie Howe. Earlier this month, former manager Liam Rosenior reminded fans that, despite the constant chatter about his short stint at Chelsea, the club had climbed to fourth place in the league table when he first took charge.

Unfortunately, that optimism has evaporated; Chelsea now sit ninth, a clear sign that the early promise has faded. The most recent 2-0 defeat to Manchester United marked the Blues' fourth consecutive loss, three of which have come at Stamford Bridge.

The string of home defeats recalls a previous run of three straight losses at the venue, including a historic setback to Oldham when Tony Cascarino was leading the line for Chelsea. These patterns suggest that the club is entering a precarious phase, and Rosenior's usually confident defence of his record is beginning to look fragile.

Rosenior has been vocal about the nature of the United loss, insisting it was unfair. "We had a chance when the opposition were reduced to ten men, but we failed to convert. We kept sending wave after wave of crosses into the box, only to see the woodwork on several occasions," he said.

"I won’t pretend to know everything, but from my perspective we dominated from the first whistle to the last. The problem lies in squandering those moments, which is why points have slipped away." There is some merit to his argument.

Opta data shows that Chelsea struck the woodwork four or five times, yet the official tally of shots on target is far lower. Since mid‑March, Chelsea have been the only side in the Premier League that has not found the net despite generating the highest volume of attempts.

This paradox—dominance without delivery—highlights a deeper inefficiency in the team’s attacking output. A closer look at the numbers reveals that United enjoyed the clearer opening chance of the match, while Chelsea’s numerous opportunities were generally of a lower quality. Over the past ten games, only Wolverhampton Wanderers have posted a lower expected‑goals (xG) per shot than Chelsea, underscoring the difficulty the Blues have in creating truly threatening chances inside the penalty area. The issue may not be purely tactical.

One cannot ignore the personnel factor. Manchester United’s Matheus Cunha, a Brazilian forward who has consistently outperformed his xG expectations, scored the decisive goal. In contrast, every Chelsea attacker who featured on Saturday has, over the course of their Premier League careers, under‑delivered relative to their expected goals. This mismatch of finishing proficiency contributes to the perception of "bad luck" but is, in reality, a symptom of a broader problem.

Football often hinges on fine margins, and it is likely only a matter of time before Chelsea break their barren spell. Yet when contemporaries such as Erling Haaland and Mohamed Salah are routinely converting their chances, the Blues’ inability to finish looks increasingly like a structural flaw rather than mere misfortune. Shifting focus to the Merseyside derby, Jamie Carragher praised Liverpool’s young talent Florian Wirtz before the match, describing his four goals and three assists as "neat and tidy" and noting that his performance should have dictated the game’s tempo.

Despite a late winner from Virgil van Dijk, Liverpool struggled to contain Wirtz, who ultimately fell short of the high expectations set for him. Statistical analysis after the game highlighted why Liverpool’s £116 million acquisition from Bayer Leverkusen remains difficult to evaluate. While Wirtz leads the league in open‑play chances created—second only to Bruno Fernandes—many of those opportunities were either poorly executed or resulted in minimal threat. For example, a clever reverse pass to Cody Gakpo fizzed out, and a through‑ball to Alexander Isak was comfortably saved.

The eye test painted a different picture. Wirtz appeared uncomfortable in a high‑tempo match, being out‑muscled and unable to impose his style. He managed only one successful dribble and failed to register a shot, raising questions about his adaptability to the Premier League’s physical demands. Although his work rate is commendable—he ranks fourth in total runs this season—his lack of decisive moments suggests a need for greater confidence and risk‑taking, traits that have defined emerging stars like Rayan Cherki at Manchester City.

Carragher acknowledged that Wirtz is still adjusting to a new league, manager, and system, but reminded fans that ten months have already passed and that tangible progress is expected. The patience window is narrowing, especially after a lackluster display against Everton. Turning to the north, Newcastle United continue to exhibit the high‑intensity pressing style that has characterised Eddie Howe’s tenure.

The club currently sits second in the league for sprint frequency, a metric they have consistently topped across Howe’s five seasons. However, this relentless approach is now exposing defensive vulnerabilities.

Newcastle’s recent 2‑1 loss to Bournemouth illustrated how a momentary lapse in press can create space for opponents. While Howe maintained that the margins were fine, Andoni Iraola’s side generated superior chances, reflected in an expected‑goals total of 2.99—the highest Newcastle have conceded this season, surpassing even the previous week’s tally against Crystal Palace. Since January, Newcastle’s expected goals against have been worse than every other Premier League side except bottom‑placed Wolves.

Their defensive frailties have placed them between three relegation‑threatened clubs, confirming that they now possess one of the leakiest backlines in the division. The home record is particularly alarming.

Newcastle have been beaten five of their last six league games at St James’ Park, matching the total number of defeats they suffered across the entire previous season and the two seasons before that combined. The once‑formidable fortress has been breached, turning what used to be a daunting venue for visitors into a more ordinary battleground.

A vulnerable Newcastle inevitably reflects on Howe’s position. Even the often‑criticised Steve Bruce never found himself as low in the table as his current charge. Consequently, Howe’s selection choices and recruitment strategy have come under intense scrutiny. Key players such as Yoane Wissa have struggled to make an impact, Anthony Elanga has once again underperformed, and Nick Woltemade’s development remains a work in progress.

Howe recognises that solutions must be found higher up the pitch, yet the immediate priority is to tighten the defence that is currently leaking goals at an alarming rate. In summary, both Chelsea and Newcastle are experiencing periods where surface statistics mask deeper concerns.

For Chelsea, the combination of abundant but low‑quality chances and a shortage of clinical finishers is eroding Rosenior’s narrative of bad luck. For Newcastle, the relentless pressing that once propelled them forward now leaves gaps that opponents exploit, putting Eddie Howe’s future under the microscope. As the season progresses, the ability of both clubs to address these structural issues will determine whether they can reverse their downward trajectories and reclaim the ambitions that once seemed within reach.
