Alastair Cook frustrated by England display

A "frustrated" Alastair Cook admits he is disappointed England are not playing to their full potential after losing by six wickets to India in Mumbai on Sunday.

England are 4-0 down in the 50-overs series and will meet in the final game in Kolkata on Tuesday.

The England skipper insists his side still have the "desire and commitment" to achieve success and will be better having experienced this "difficult" series.
