Ireland number eight Jamie Heaslip talks of his admiration for his Wales opposite number Taulupe Faletau ahead of Sunday's Six Nations game in Dublin.
"I'd love to be able to hate the guy but he's such a nice guy off the field," said Heaslip of his British & Irish Lions team-mate in 2013.
"I do respect him a lot on the field. That makes you put in your work and do extra around training in the player room or in the gym.
"We're going to have our work cut out and I've tried to tell Tommy (O'Donnell) and CJ (Stander) what we're going to be up against.
"Wales have a very well-rounded back row and we're going to have a massive challenge on Sunday."
