Rory McIlroy's Open X-factor pinpointed as former Ryder Cup captain insists even rivals are wowed by star

Thomas Bjorn believes Rory McIlroy is the X Factor at The Open Championship. Bjorns was runner-up to Tiger Woods in 2000 at the Home of Golf. He believes time is running out for McIroy to win the Claret Jug at St Andrews. BjORN skippered Europe to victory over the United States at Le Golf National in 2010. The Dane believes the Open is a celebration of everything golf stands for. It's the power of the Championship that gets Bjor's juices flowing. His advice to McIIroy would be to focus on the tournament itself. Mciiroy came third on his St. Andrews debut in 2009 and was favourite to defend his title in 2015.
