Ireland scrum-half Eoin Reddan is backing his Leinster team-mates Josh van der Flier and Garry Ringrose to make an impact at Test level.
Both players were included in Ireland's training camp on Sunday as Joe Schmidt prepares for the Six Nations.
Reddan believes the pair can make a real impact if Schmidt decides they're ready to make the step up.
"I'm not surprised at all that people are talking about them and they're lucky to have people like [Leinster coach] Leo Cullen and Joe Schmidt in charge of them and between those two coaches, they'll manage the situation perfectly," Reddan told the Irish Independent.
"If they're ready, they'll play. And if the coaches feel a longer path is necessary, they'll take that if they have to.
"But if you're asking me if I'd mind ever lining out beside them in any kind of jersey then the answer would have to be no, because I think they're both great players.
"They're excellent, they're great to have around Leinster, too. They are technically really good at their jobs, very good tacklers, very good over the ball.
"They have to be because they're young. When they get their chance they're taking it. They're carrying out details of their jobs to the letter of what they're supposed to do.
"That helps all us older lads to just see their commitment to their role. They're definitely leading the group."
