Commenting on Saturday's top of the table clash, Ulster hooker Andy Kyriacou said: "Obviously last weekend (against Edinburgh) was a massive disappointment for us, but we're not going to dwell on it.
"The only game that matters now is Leinster at Ravenhill on Saturday.
"It's first versus second and everyone is really excited about it. I think that goes for the supporters as well.
"Ravenhill was really kicking in terms of atmosphere for the Bath game and I'd expect it to be the same at the weekend."
