Dublin - Ireland captain Rory Best has revealed he is keen to sort out his future before the Six Nations, saying that he could continue until 2019.
Best was man-of-the-match for Ulster in their recent Champions Cup win over La Rochelle and admits he is feeling confident about his form.
However, aged 35, the vastly experienced hooker is approaching the closing stages of his career and it remains to be seen whether Ireland head coach Joe Schmidt views him as the long-term option looking ahead to the 2019 Rugby World Cup, with Best then to be 37 years of age.
"I will sit down with the IRFU and with (Ireland coach) Joe Schmidt and I will make a decision on that in the next couple of weeks," Best told BBC Sport.
"I would like it sorted out before the Six Nations so I can concentrate on playing."
He added: "If the World Cup started right now I would have no problem, but you would need a crystal ball to know what I will be like.
"Right now I still feel I can play for Ireland at the top, top level and World Cup rugby is the top level."
