Brian O'Driscoll didn't stutter when naming his five toughest opponents

The former Leinster star, who racked up 133 caps for Ireland and led his country with distinction, was never one to shy away from a challenge. Now, the man known for his sharp footwork, unmatched rugby brain, and sheer grit has named the players who made life hardest on the pitch.

O’Driscoll’s list offers a glimpse into the fierce battles at the heart of Test rugby – a world where only the very best survive. From bruising tacklers to elusive attackers, these are the names that earned his respect the hard way.

Still revered today as a rugby ambassador and role model, O’Driscoll’s reflections are a must-read for fans who followed his journey – and for those who dream of stepping into his boots.

Sourcing several Q&A’s from down the years, including one with the Six Nations website, here are his top five opponents:

Known initially more for his braided hair and eyeliner, he added passing and kicking to his raw line-breaking power to become one of the great centres, capping his Test career with that superb World Cup final try.

Brian O'Driscoll SAID: "Same height as me [5-foot-11] and still 16-stone. Probably the most complete centre in the modern game."

Nicknamed The Snake because of his ability to slither through the smallest of gaps and strike with a sudden burst of speed. Brought fluidity to the All Blacks midfield with his intelligent passing and vision.

Brian O'Driscoll SAID: “I thought Conrad Smith was always one of the really difficult ones. He was nicknamed ‘Snake’ I think because of his hips and it doesn’t look like he’s going that fast but jeez, he can travel."

The ultimate players’ player. Did all the unseen, grafting work and just got on with his job in unassuming fashion, putting his body on the line. Able to excel right across the back row, he was a pivotal figure on two Lions trips and an England World Cup winner.

Brian O'Driscoll SAID: "Richard Hill, England No.6 that won the World Cup in 2003. He was a brilliant teammate but he made that team tick, he was the unsung hero in that world cup win. He was hard! I always liked playing with guys that were nails in the team, that really stood up and never took a backwards step."

The 73-cap France international was a member of the Toulouse team that reached the Heineken Cup final in 2003, 2004 and 2005, winning in 2003 and 2005. The centre was named as the man of the match in the 2005 Heineken Cup Final as Toulouse defeated Stade Français. 

Brian O'Driscoll SAID: "Jauzion was just incredible and was so hard to stop, with his offloading ability. France built so much off and around him. 6-foot-4 and probably 17-stone."

WIlkinson garnered 1,246 during his 97 caps for England and the Lions. His finest hour, of course, came in 2003, when he slotted the drop goal that won the World Cup.

Brian O'Driscoll SAID: “Even to just get a snapshot of what his mind works like now and how he thinks about things is pretty eye-opening as to what sort of detail he went into as a player,”

“He’s an out-and-out perfectionist, he just needs that 10 out of 10. I don’t think you ever achieve it and I think he beats himself up about it, but he got pretty close to 10 a lot of times.”

You've got just 5 minutes on the clock – no pressure!
