Sunderland boss Martin O'Neill is convinced Lee Cattermole is good enough for England.

The 24-year-old midfielder, who faces home-town club Middlesbrough on Tuesday, has played at every level for his country but has failed to break into the senior squad.

O'Neill said: "Why shouldn't he think of England? Maybe after all this time there is no definition of his role and that is something over this season, and next, if he stays injury-free, that could be more defined."
