Chelsea lost for the third time in the Premier League this season, as the Blues fell to a 2-1 defeat away at Crystal Palace.
Chelsea were expected to take all three points against a Palace side that hadn’t scored a goal all season, but the Blues were stunned at Selhurst Park.
Cahill after the game revealed how disappointed the team was.
“At this moment in time we are not having the best of luck with injuries,” Cahill said.
“We are in a difficult moment in terms of missing players. It’s not a huge squad and that plays a part, but nevertheless we have got enough out there to produce a much better performance than what we did. The effort was there but the quality? We can definitely do better than that.
“We are massively disappointed first and foremost with the result but also the quality of the performance we put in. We need to do more.
“The best thing when you have a performance like that is to play as soon as possible. We have got an important game coming up midweek and we know we can do better.”
