And the Warriors winger believes victory could be a springboard for further success this season.
He said: "It is an opportunity to close the gap between us and the sides above us in the table.
"We have what it takes to beat a lot of sides and if we can get a result on Saturday, we will be in a good position going forward for the rest of the season."
Warriors were narrowly beaten by the Exiles at Sixways in the early stages of the season despite dominating large periods of the match.
But Drauniniu feels his side have made huge strides since the last meeting between the two clubs in September.
He admits: "Irish are a decent side but it was frustrating against them at Sixways and we should have won that game.
"But we have a good team now, we are growing in confidence and we know our systems and structures well.
"We're looking forward to the game and we have every confidence that we can notch up that first win."
Warriors produced a dominant second-half display against an international-blessed Saracens side last weekend.
And the back insists Warriors have gained a great deal of confidence after having put the league leaders under significant pressure.
He added: "I think it was a positive performance, especially from the forwards. They challenged the Sarries pack in every aspect of the game.
"How we played in the second-half will give us great confidence going forward. We've grown in the last eight weeks. There has been massive improvement."
