Liam Rosenior has said Chelsea must ‘eradicate’ their set-piece and disciplinary issues if the club are to have a successful season.Chelsea lost 2-1 to Arsenal in the Premier League on Sunday, in a blow to their Champions League qualification hopes. The Blues conceded twice from corner kicks at the Emirates, while their hopes of a comeback were not helped by Pedro Neto’s red card. That dismissal was Chelsea’s ninth of the campaign in all competitions.“If we don’t eradicate the set-play issues that have started to creep into our game and our discipline issues, then for all of the good things we do in the game, we are not going to get what we want to achieve,” Rosenior said to BBC Radio 5 Live at full-time.“I have respect for the previous manager Enzo [Maresca]. I don’t speak about what happened before but it is starting to happen with me. (adsbygoogle = window.adsbygoogle || []).push({});“It’s something I felt we had addressed. We went 10 games without a red card, now [we have had] two in two games and that’s a problem we need to solve.”In the nine games that Chelsea have been reduced to 10 men this season, the Blues have won just three times. Their red cards include dismissals in both league fixtures with Arsenal and a costly red in a West London Derby defeat to Fulham.Pedro Neto's dismissal against Arsenal means Chelsea have now received the joint-most red cards by a team in a single Premier League season… and they still have ten games to play pic.twitter.com/YnxaZjFS8o— Sky Sports Premier League (@SkySportsPL) March 1, 2026 Chelsea players sent off this seasonRobert Sanchez, Manchester United, Lost 2-1Trevoh Chalobah, Brighton, Lost 3-1Joao Pedro, Benfica (Champions League), Won 1-0Malo Gusto, Nottingham Forest, Won 3-0Liam Delap, Wolves (EFL Cup), Won 4-3Moises Caicedo, Arsenal, Drew 1-1Marc Cucurella, Fulham, Lost 2-1Wesley Fofana, Brighton, Drew 1-1Pedro Neto, Arsenal, Lost 2-1Read – Premier League Awards – Pickford’s super save, Sorry SpursSee more – Premier League Team of the Week – Pickford, Damsgaard, IwobiFollow the Football Faithful on Social Media:Facebook | Instagram | Twitter | YouTubeThe post Every Chelsea player sent off this season as total reaches nine first appeared on The Football Faithful.
