Sunderland secured a 1-0 home victory over Chelsea at the Stadium of Light, with Enzo Le Fee converting a 36th-minute penalty after Brian Brobbey was brought down by Levi Colwill.
Chelsea manager Xabi Alonso made further changes to his formation, fielding a three-man midfield for the first time this season and again operating without a recognised striker, with Pedro Neto deployed up front. The visitors dominated possession with 68.7% but created few clear chances, while Morgan Rogers missed a headed opportunity and Cole Palmer struggled days after being omitted from the England squad.
Alonso refused to criticise the officials after Chelsea were denied a penalty when Palmer went down under Luke O'Nien, with VAR ruling the contact started outside the box. The Spaniard instead focused on his side's failure to execute the game plan, stating Brobbey was "stoppable" but Chelsea defended poorly. Colwill was substituted at half-time, with Moises Caicedo filling in at centre-back despite limited training time.
Injuries have forced constant lineup changes; Chelsea have made 24 starting XI alterations in the Premier League this season, second only to Tottenham's 28. Key absentees include Reece James, Joao Pedro, Emiliano Martinez, Maxence Lacroix and Jorrel Hato. Alonso acknowledged the squad shortages, saying they must "walk through this step" while awaiting returns.
Despite the loss, Chelsea sit fifth with five wins, four losses and a draw from ten league games, five points better than the equivalent fixtures last season. However, the team has conceded 50 shots on target – only Crystal Palace have allowed more – and Alonso remains searching for a consistent identity ahead of the November international break.
