But the 36-year-old former London Wasps back row star has claimed the sensational series victory over the Springboks with the 1997 Lions remains his most treasured memory.
"When I look back at my career, that 1997 Lions tour is probably the highlight for me," said Dallaglio, who started all three Tests against the Springboks and took part in two further tours with the Lions in 2001 and 2005.
"To win a Lions series in South Africa was stunning - the best experience of my life.
"We had wonderful players. I made friendships on that trip that will last a lifetime.
"That South African team was the most physical I ever faced and Andre Venter stood out them. He was a very tough, physical player. But we had 45,000 fans cheering us on and that was a wonderful feeling."
Dallaglio made a total of nine appearances for the Lions in all three major touring venues and the charismatic Englishman believes nothing else can compare to what the Lions has to offer.
"The Lions is a great concept," Dallaglio told Sky Sports Magazine.
"You spend four years kicking lumps out of each other, then you get put into a hotel together and a few weeks later you're up against one of the best teams in the world. It's fantastic."
