Clarke 'happy' about Compton omission

Australia captain Michael Clarke says he is 'happy' about Nick Compton's omission from the England team in favour of Joe Root.

Compton scored 81 and 79 against Australia in warm up matches but poor recent test form saw him lose his place at the top of the order.

Root will open the batting with captain Alastair Cook when the Ashes get under way at Trent Bridge.
