British and Irish Lions head coach Warren Gatland says he's not worried about Johnny Sexton and Owen Farrell's lack of experience starting together ahead of the second Test with New Zealand.

They'll play at 10 and 12 in Wellington on Saturday. Sam Warburton returns as captain - with Maro Itoje earning a place in the starting XV.

But it's the Sexton-Farrell combination that Gatland's being asked about most.

"They haven't started together but they have had quite a bit of time together," he said. "The combination against Crusaders was good and they had a bit of time together last week. 

"It's given us two ball players and two kicking options on the right foot and the left foot with Jonathan Davies and Elliot Daly as well."
