The player’s drop goal helped Thunder to a narrow 15-14 win over Hemel Stags in their opening play-off game at the weekend.
“It’s going to be a tough game at Hunslet on Sunday: they are big, physical and experienced team with plenty of good players in their side,” said Beharrell, who is dual-registered with Gateshead from Hull KR.
“If we carry over this confidence to their place and play like we know we can play then we can beat any team on our day.”
Beharrell is enjoying his time in the North East of England, and thinks that good times are ahead for both Thunder and the sport in general.
“I’m really enjoying my rugby at Gateshead and they’re a great bunch of lads to play with which helps,” he added.
“We’ve done better than everyone expected us to do this season.
“The game against Hemel Stags was a fantastic experience because it was part of a double-header. Our game was straight after Newcastle Falcons played London Irish and it was pleasing to see a lot of their fans sticking around to cheer us on too.
“There’s a real buzz around Gateshead at the moment and it’s exciting times for the club. With Stanley Gene being here and Newcastle Falcons taking over hopefully the good times will return.
“Stan’s put the structure in place and we all know what is required of us at the weekend. Anything is possible and fingers crossed it’ll go our way.”
