O'Driscoll calls for Leinster discipline

Brian O'Driscoll says Leinster must not hand penalty chances to Ulster kicker Ruan Pienaar in Saturday's Heineken Cup final.

"Discipline is going to be key when you have a guy [Pienaar] that is going to be able to knock over penalties from 55 or 60 [metres] out," said O'Driscoll.

Saturday's clash is the first ever all-Irish final in the European competition.
