As multiple Saints youngsters return from last week's international exploits, Under-23s coach Radhi Jaïdi is hoping their experience will further enhance performances at club level.
Teenage pairing Thomas O'Connor and Jonathon Afolabi both played for Ireland's Under-19s in their Euro qualifying campaign, with the latter netting twice, as the remainder of the Under-23s squad have been preparing to face Newcastle at St Mary's tonight.
Previewing the game, Jaïdi said: "We want the players to keep the momentum from any positive results or success at any level. We've had some international boys away on duty, and we want them to bring that positive mentality to their club football.
"We've been working hard, keeping the boys focused and concentrated on the next objectives. We'd have liked a game this week but obviously there have been internationals. It is a break, and an opportunity for us to revisit some details."
Asked if stadium games provide the younger players with added incentive, Jaïdi said: "It is always good to play at St Mary's. It isn't going to be full up like the seniors, but it will give the boys some reference of how the first-team players feel and their experience on a Saturday.
"We expect an intensive game, in terms of the way they play. High-tempo, a lot of rotation between midfielders and wide players. Hopefully we'll respond positively."
