Liam Rosenior's first Premier League game as Chelsea's head coach ended in a 2-0 victory against Brentford at Stamford Bridge on Saturday. Goals from Joao Pedro and Cole Palmer secured the win, but Rosenior admitted the team struggled in the second half due to a virus affecting the squad.

Chelsea had been battling a virus within the club during the week leading up to the game. Liam Delap and Jamie Gittens were sidelined for the Carabao Cup match against Arsenal due to illness, and were still recovering at home with high temperatures. Several staff members were also affected. Rosenior held a meeting with the players to emphasize the importance of hygiene, reminding them to wash their hands to contain the spread.

Despite the illness affecting the team, Chelsea managed to take the lead in the 26th minute when a deflected clearance fell to Joao Pedro, who fired a shot into the net. The goal was initially ruled offside but was overturned by VAR. Brentford had opportunities to equalize, with Mathias Jensen's volley hitting the post. Alejandro Garnacho also missed a clear chance from close range.

In the second half, Brentford continued to create chances, with Robert Sánchez making a crucial save to deny Kevin Schade. Igor Thiago's header also went narrowly wide. However, Chelsea extended their lead when Liam Delap was brought down by goalkeeper Caoimhín Kelleher, and Cole Palmer converted the resulting penalty.

Rosenior acknowledged that Chelsea were fortunate to win, and that Brentford squandered several opportunities. He said the virus impacted the team's performance in the second half. "The club doctors are doing everything they can to contain what looks to be a virus because some members of our staff have come down with it as well," Rosenior said. "We had a meeting today with the players about washing your hands, the basics, which is really important and hopefully we can contain it. We have a busy period so we need everyone ready to go and fit and healthy".

Despite the challenges, Rosenior was pleased with the result, which marked his first Premier League win as Chelsea manager. The victory moved Chelsea up to sixth in the Premier League table, while Brentford dropped to seventh.

In other news, Rosenior provided updates on Romeo Lavia, who is recovering from injury and is close to returning to training. He also addressed the situation of Facundo Buonanotte, whose loan from Brighton may be terminated so he can move to Leeds.
