Ahead of their quarter-final showdown in the European Challenge Cup on Saturday, Newport Gwent Dragons' Taulupe Faletau and Cardiff Blues' Sam Warburton went head to head to see who could stare the other man down.

The Wales and British and Irish Lions team-mates, who have 102 Test caps between them, have seen both their sides have a disappointing Pro12 season.

But both regions lost only once in the Challenge Cup group stages, while Blues won at Rodney Parade in the league in January.

Tune into Sport Wales from 19:00 GMT on BBC Two Wales on Friday for our European Challenge Cup quarter-final preview, and follow the match live on BBC Radio Wales and the BBC Sport Wales website from 12:30 GMT on Saturday.
