Rosenior expresses frustration over easy concessions as Everton deliver significant setback to Chelsea

Chelsea hold on to sixth position with 48 points after 31 fixtures, whereas Everton climb to seventh on 46 points from an identical number of outings, mounting a strong challenge for a European spot in the upcoming campaign.

Beto netted his opener in the 33rd minute following an excellent delivery from James Garner, who marked his recent England squad inclusion with a standout performance, prior to slotting home a follow-up effort shortly after the hour by threading it between the legs of Chelsea custodian Robert Sanchez.

Iliman Ndiaye sealed an impressive third goal with 14 minutes remaining, bending the shot into the upper corner, marking Evertons largest triumph against Chelsea since 1987 and their initial consecutive victories at the modern venue along the River Mersey.

Chelsea have now suffered defeats in four successive matches across all tournaments and endured a challenging period that also saw them eliminated from the Champions League at the hands of Paris Saint-Germain.

The onus and ownership lie with me, Rosenior stated to Sky Sports. We arranged the side in a slightly altered manner today, focusing on a 4-4-2 formation, and I felt we were in control before Everton broke the deadlock.

The key factor was in the penalty areas on both ends, where they proved sharp and Ndiayes strike was exceptional.

Rosenior voiced dissatisfaction regarding how his team allowed the initial pair of goals and noted it as a recurring issue recently.

Scoring lifts your momentum, yet currently we are handing over goals too freely, he commented. We began tentatively but gradually found our rhythm.

However it occurs far too frequently that we concede inexpensive goals, boosting the opponents morale and the atmosphere, while their assurance surges.

Everton earned the win convincingly, and it is an aspect we must address promptly.

Garner has now recorded six Premier League assists this term, up from a mere four across his previous professional tenure, a surge that earned him a place in the England setup.

I am absolutely delighted, beyond words. It is a lifelong ambition, he remarked. The England coach Thomas Tuchel contacted me to confirm my participation; it has been an astonishing week, capped perfectly by this success.
