Al Jazeera's Louise Potter speaks to Europe's victorious 2010 Ryder Cup captain Colin Montgomerie and golf's world number seven Paul Casey at the launch of Powerplay Golf at Celtic Manor.

On the agenda are Montgomerie's thoughts on Rory McIlroy's capitulation in the final round of the US Masters, and whether the five-time major runner-up thinks the young Northern Irishman can go one better than him and win a green jacket.

Casey gives his thoughts on Masters winner Charl Schwartzel and explains why he hopes Tiger Woods beats Jack Nicklaus' record of major championship wins.
