Leinster are a quality side - but Ulster can beat them if they play to their best.
That was the opinion of Ireland captain Rory Best, speaking to reporters at a Kingspan Media Day ahead of Ulster's crunch last home match in the Guinness Pro-12.
A win against the league leaders will almost certainly guarantee the Ulster men a place in the last-four play-off stage.
"Leinster are a quality side of course. Being from Ireland and playing on the international scene, I know so many of their players so well. we all do.
"We know how good they are - but for us a lot of the challenges are around ourselves to ensure we perform.
"And we know, especially at home, if we perform to the best of our ability, that we are very, very hard to beat.
"And we know against a quality side like Leinster, we have to produce that this weekend," he insisted.
