Attack coach Alex King has tipped Cam Dolan and Joel Hodgson to star for Saints this season.
USA No.8 Dolan arrived at Franklin’s Gardens in December, but has yet to play a first-team game for the club.
Hodgson moved to Saints from Newcastle during the summer and will provide competition at scrum-half and fly-half.
King’s hopes for the duo are high and he expects them to add plenty to a squad which claimed Aviva Premiership and Amlin Challenge Cup glory last season.
“Cam trained with us for four months of the year and didn’t get in the side because of the form of Samu (Manoa) and Sam Dickinson, but he’s been really impressive in training and I can’t wait to see him (in the friendly against Rotherham) at the weekend to see what he can bring to the team,” said King.
“He’s a guy full of energy, athletic and he’s got really good skills for a back row.
“Joel is on his way back from his wrist injury as is not too far away, but when he gets back he’ll bring a real freshness to nine and 10, depending on where he plays.”
