The Lions, after losing their first four Celtic League fixtures, made it three on the trot when they triumphed 31-10 at Glasgow Rugby last Friday.
But the Scarlets are on an identical winning streak and former Wallaby centre Ella is wary of what he calls “the most experienced and stable team in the tournament at the moment. They are a very good side with bucket loads of experience.
“Of course we will take the three wins and, while I have not been disappointed with the performances, I know we can still play better.
“It will be good to get our leading players back when I will expect us to produce good, consistent rugby.
“But the wins certainly make it a lot easier for everyone – faces are cheerful, it increases the confidence of the players and they are also willing to put in those extra few yards in training.
“We have been looking at tapes of the Scarlets, and some of our guys know their players quite well, but it is going to be a tough one.”
