O'Neill praises 'terrific effort'

Sunderland manager Martin O'Neill praises the "terrific effort" of his players after they hold Arsenal to a 0-0 draw at the Emirates on Saturday.

The Black Cats frustrated Arsene Wenger's side as they shared a point apiece on the opening day of the season.

O'Neill also says it would be "a concern" if Sunderland fail to bring in another striker before the transfer window ends on 31 August.
