Brian O'Driscoll has told Ireland to expect some typically ferocious tackling from Samoa at the Aviva Stadium on Saturday.
The Pacific islanders, who are embarking on a three-Test tour of the UK and Ireland, are renowned for their bone-jarring hits as executed by the likes of Alesana Tuilagi and Seilala Mapusua. While O'Driscoll has seen first hand the damage they can do, he insists their kamikaze style can leave gaps to be exploited.
"We don't have a huge amount of footage on Samoa but we do know some of their personnel, particularly the guys playing in England," said Ireland's captain.
"The one thing you get with Pacific islands teams is huge physicality.
"Their players are capable of putting a hole in you if you run directly at them.
"That being said, you must be aware of the shooters that can come out of their defence on occasion.
"Sometimes you have to play smarter, if their line speed is huge then play the ball behind them.
"But at the same time we shouldn't be afraid to play if the conditions allow us to."
