The 31-year-old Grand Slam winner is expected to line-up for the Men of Gwent for their second Welsh derby in as many weeks.
And Sidoli is hoping the Rodney Parade crowd can prove the difference when the Dragons take on the Scarlets on Friday night.
“Playing at Rodney Parade gives us a massive boost”, said Sidoli, whose Dragons side were beaten by the Blues at the Cardiff City Stadium last weekend.
“It is definitely something we thrive off. I think some teams enjoy it as much as others are intimidated.
“They are very vocal, are up on their feet and it certainly gives us extra confidence.”
The Dragons will be hoping to make amends for last week’s 43-21 loss at their closest rivals while the Scarlets travel to Rodney Parade having recorded two consecutive bonus-point victories after their disappointing opening-day loss at Benetton Treviso.
But despite their failings at the Blues and at Connacht, Sidoli is confident the Dragons can get a positive result if they play with confidence.
“Home games are obviously very important”, added Sidoli.
“We struggled against the Scarlets last year so it would be nice to get a performance against them on Friday night. With just four regions, any time you play a Welsh team it is a big derby.
“Both sides have struggled with injuries so it will test the squads, especially being early in the season.
“But I think our pack and back-line are very good – especially at home.
“We have a very passionate side and play for each other. We need to replicate that in away games but at home we’re a match for anybody.
“We have to be confident. Against the Scarlets last year at Rodney Parade we gave the game away.
“Our games against them are always high-intensity, they are good quality and go right down to the wire. It will be definitely a big test for us.”
