However, the rock solid hooker admits he can hardly wait for the test himself against the league's top side and believes Warriors must just concentrate on their own performance to gain a big result.
"Saracens look sharp at the moment as they are unbeaten, but for us it is a big challenge for this week and I am excited by this," said Lutui.
"This time we will look to stop their unbeaten run - the result could be big for us.
"We have to look at ourselves now. We realise that every week it will be a tough challenge, there are no easy games in Guinness Premiership so this is no different.
"If you look at the table there is not much between teams. We have to concentrate on our game and not elsewhere, if we focus on our preparation and make sure we get it right we can perform.
"We know Saracens are in good form and have not lost, but we must not think about that, just focus on ourselves and what we can do."
