The duo were impressive figures in a 3-2 loss to Liverpool in the Premier League on Sunday.
While the Saints did not get anything from the game, Martin acknowledged the youngsters were brilliant again.
He stated post-game to reporters: “Yeah, they're really talented. I think they have to play in a certain team in a certain way right now at their age to flourish and to show what they can do.
“If you put them in a different team that are fighting down the bottom, maybe they look very different or they're not playing because their skill set is not suited.
“Their skill set is taking the ball and being brave, taking it in tight areas and beating their player. They're getting better and better all the time.
“We have to keep working, they have an amazing mentality. They will keep growing with us or they'll outgrow the club and the club will benefit hugely from that.
