Leandro Trossard has acknowledged that Arsenal need to be more clinical in front of goal if they hope to improve their performance against Chelsea. Mikel Arteta's team has not secured a Premier League victory since October 5 and recently suffered a defeat to Inter in the Champions League, where they managed 21 shots but only hit the target four times, failing to score for the second consecutive match. With captain Martin Ødegaard sidelined due to injury, Trossard has taken on additional creative duties. Ødegaard is anticipated to make a return at Stamford Bridge on Sunday, which could provide a much-needed boost for the team as they prepare for the London derby.
