Chelsea have not defeated Brentford in the Premier League since the 2021-22 season, when they secured a 1-0 victory with Ben Chilwell scoring the only goal. Since then, every meeting between the two west London clubs has ended in a draw. This season, the contrast in their approaches has become more apparent, with Brentford showing strong defensive consistency, while Chelsea are still adjusting to their latest managerial and tactical changes under Xabi Alonso. Kevin Schade, who scored twice against Bournemouth, will look to test Chelsea’s defense, which is still adapting to Alonso’s system. Only one Premier League title-winning team has used a three-man defensive line, and that was Chelsea’s 2016-17 squad under Antonio Conte. Alonso’s attacking style has proven more effective, presenting a challenge for Jannik Schuster, who made his first Premier League start in place of Nathan Collins. Schuster faced a tough test from Bournemouth’s Evanilson but performed well. Meanwhile, João Pedro has been a key player for Chelsea, contributing three goals and three assists, though his fitness is in question, which could lead to Danny Welbeck’s first league start. Aston Villa’s visit to Tottenham Hotspur Stadium on Saturday will see two teams hoping to secure their first Premier League win of the season. Both have scored just one goal in their opening four matches. Tottenham’s return of Pedro Porro could signal an end to the uncertain experiment with Archie Gray at right-back. However, Spurs' starting XI feels unsettled, with many players appearing to be on the edge of being replaced. James Maddison, who has been sidelined by injuries, is eager to return and provide some attacking spark. For Aston Villa, the challenge will be to break through a Tottenham defense that has struggled to find consistency. Brighton’s 20-year-old forward Malick Yalcouyé has emerged as a key player this season, scoring twice in the Premier League after a loan spell at Sturm Graz and Swansea. His rise has been notable, especially with Jack Hinshelwood injured, and he will be a threat against Arsenal, who are next on Brighton’s schedule. Meanwhile, Everton’s Vitalii Mykolenko has improved significantly this season, helping the team keep four clean sheets in six games. Despite concerns over left-back cover after loaning out Adam Aznou, Mykolenko has silenced critics and will face a test from Ipswich’s new forward recruits. Newcastle United’s new manager Matthias Jaissle has ruled out switching to a back five or altering his "vertical" approach, despite a heavy defeat at Leeds and a string of injuries. He remains committed to his vision for the team, even as they adapt to life without key players like Bruno Guimarães. For Nottingham Forest, Liam Delap is finding his footing, showing promise as a striker and forming a good partnership with Morgan Gibbs-White. The club is also preparing for a major stadium expansion, which has been approved by the local council. Meanwhile, Andoni Iraola will return to Bournemouth, where he led the team to their best-ever league finish, and will face a team under his former assistant, Marco Rose. Dominic Calvert-Lewin is aiming to break a long-standing Leeds record with a goal against Crystal Palace, and Manchester City’s strong start to the season has made them serious title contenders. Fulham’s Oscar Bobb, who scored a crucial goal in the Carabao Cup, will look to make an impact in his upcoming match against Manchester United.
