Harlequins back-row Will Evans said there are “a few more intimidating grounds" than Saracens’ stadium ahead of their Premiership semi-final clash.
Saturday’s meeting will be the fourth London derby between the pair this season, with Sarries having won each of the previous three.
The 10,500-seater StoneX Stadium is said to have sold-out, with Harlequins selling their 2,000-seat allocation within minutes of the tickets becoming available.
Flanker Evans suggests that the travelling Quins support will be able to make their presence felt in north London and roar Tabai Matson’s side on to a second consecutive final.
“We know it's not going to be an easy task this weekend,” the 25-year-old told BBC Radio London.
“They're a very hard team to beat at home but every single one of us, all 23, are going to play and believe we can do it.”
Evans missed the end of last season due to injury as Quins produced a dramatic late comeback to beat Bristol Bears at this stage before recording another sensational victory in the final against Exeter Chiefs.
Asked whether Quins can replicate their previous semi-final heroics, Evans said: "They're too good to give up a 28-0 deficit. We've spoken a lot about that, to stay on their coat tails in the first half and don't let them build up too much of a lead."
Given their head-to-head record this season and higher finish in the Premiership table, Saracens head into the weekend’s tie as favourites.
But Quins defied the odds last season, beating the top two teams from the regular league standings on their way to a second Premiership crown.
“Last season we were in a bit of a tough place and were towards the lower end of the table,” scrum-half Lewis Gjaltema told the club’s website.
“But we believed in ourselves and our ability and managed to go on and win the Premiership.
“This season we have the champions tag on our back and through strong performances have put ourselves in the position to go on and challenge for the title again.”
Quins are the only side to have made the last four in both of the last two seasons, and a linchpin of their recent success has been the club’s record try-scorer, Danny Care.
The former England No.9 was named in the BT Sport team of the season and has been influential to the development of current England star, Marcus Smith.
“It’s amazing to watch DC day in, day out and how he approaches work each day,” said Gjaltema.
“You learn so much from players like him and I will just keep chipping away at his heels and hopefully I’ll get a shot to feature in the nine shirt going forward.
“Obviously, I would love to be playing each week, but when someone is in the form DC is in it’s hard to take the starting spot away from him.”
