James Anderson expects England improvement

England bowler James Anderson has admitted that there is room for improvement in the Test side, despite winning the Ashes series.

Alastair Cook's side defeated Australia 3-0 to retain the urn.

Despite not losing a Test, Anderson has said that the team has more to offer.

"From a team point of view, I would say we were comfortably 30% below our ability and potential," Clubcall.com quotes Anderson as saying.

"We had to fight and scrap our way to winning the crucial moments in each Test."

England are currently facing the Australians in a one-day international series.
