Following the conclusion of the Six Nations, there is plenty of speculation as to who will be selected for the Lions tour this summer and especially which player will be handed the armband.
Gatland has plenty to think about between now and his squad selection but the New Zealander is adamant his decision for the captaincy needs to be at the top of his game on the tour.
"The captain's form has to be good enough," he said on Sportsweek. "I think whoever that person is has to rise to that, the message to that person is it's a great honour to captain the Lions but your form has to be good enough to be selected for the Tests."
One man who has been linked with the role once again is the 2013 skipper Sam Warburton and Gatland has revealed the Wales flanker is in contention for the position.
He added: "He's (Warburton) a different captain to some other players. He leads by example. He doesn't say a lot but he has that experience.
"He's one of the guys in contention, definitely. In my mind there's probably half a dozen people in contention."
