Wales Online's Simon Thomas provides his take on how Wales can stop Paul O'Connell.
"It's 10 years virtually to the day since Paul O’Connell won his first cap against Wales – not that he remembers much about it!
In theory, your Test debut should be an unforgettable occasion, but it was exactly the opposite for the big Munster second-row.
O’Connell was concussed less than 10 minutes into the 2002 Six Nations clash at Lansdowne Road, when he sustained a heavy knock to the head in a collision with opposing lock Craig Quinnell.
But, not only did he stay on, he actually scored a try as he helped Ireland secure a 54-10 victory that proved the final straw for Wales coach Graham Henry.
Now, a decade on, he will be looking to lead his country to another Dublin triumph over the Welsh – and, this time, one that he will be able to remember."
