Sean O'Brien: We must shut down Mathieu Bastareaud to beat France

Ireland must shut down powerhouse Mathieu Bastareaud to beat France and avoid New Zealand in the World Cup quarter-finals, according to Sean O’Brien.

Toulon centre Bastareaud will attempt to terrorise Ireland’s defence in Sunday’s Pool D decider in Cardiff, with flanker O’Brien accepting Joe Schmidt’s men must deny the 27-year-old any room to run.
