"We have won three out of three now and the end of season is now in sight and we know what we have to do," he said.
"We are playing well at the moment and need to keep doing that.

"I watched Ulster last night and they are a really good side.
"They are winning games and on a good run and we know it is going to be tough.

"We know at our best we are a good side and capable of winning the game."
