Ryder Cup 2012: McIlroy invites USA to 'take him on'

Rory McIlroy says it is a compliment that United States think he is the man to beat at this year's Ryder Cup, and invites his rivals to "take him on".

McIlroy goes into this week's event at Medinah as the world number one and a "marked man" according to Tiger Woods.

McIlroy's Europe team-mate Ian Poulter also speaks about the rivalry with USA, admiting that players who are usually "great mates" will be going out to "kill" one another's chances of glory.
