Chelsea defender Gary Cahill says Arsenal will be title contenders this season.
Alex Oxlade-Chamberlain's only goal of the game secured a 1-0 win for the Gunners against the Premier League champions at Wembley on Sunday afternoon.
And Cahill - who says Chelsea deserved more for their performance - believes Arsene Wenger's men have enough quality to fight for the Premier League crown.
"Let's be fair, the game's been won on a piece of individual play to smash it in the top corner, but chance-wise we had the majority of the play," Cahill told the club's official website.
"I think in terms of possession we had the majority of the game but it's the scoreline that matters and we're disappointed with that.
"They started the game well, but in the second half it was the opposite of that we felt we were on top and they were sat back, and we had a lot of ball in their half. We did everything to score.
"They've started well, they've got a good squad and I think they'll be one of many pushing at the top this season.
"I'm sure everyone has that belief at the start of the season. People talk and talk but the bottom line is when the season starts.
"We're confident, we have a good squad and still have another game on Wednesday [against Fiorentina], and more time to train before we start. We'll be strong but it's a tough league and everyone else will be strong as well."
