Ross Barkley believes Chelsea have already shown they can beat Liverpool.

The two clubs will meet at Stamford Bridge this Sunday for their second meeting of the season after Liverpool defeated the Blues on penalties in the Super Cup final last month.

"Every side is beatable on the day. It just goes down to hard work, putting extra yards in, being clinical as well and a bit of luck. The big games bring the best out of all players," Barkley told reporters.

"As you have seen in the Super Cup final and how well we performed in that game, and we can perform to those levels again on Sunday and hopefully it goes our way.

"We are joint-third [in the league on points]. We're not doing badly. We won at the weekend, scoring goals. We have got a confident bunch of lads in the team. We have got a big game on Sunday and we are confident we can win the game."
