The Belgian teenager Florent Cuvelier made 18 appearances and scored four goals during a temporary spell with League One side Walsall last season, and Pulis is backing the former Portsmouth man to reach the highest level.
Current first-team players Ryan Shotton and Andy Wilkinson have benefitted from loan spells away from the Britannia, and Pulis cites the 'sink-or-swim' nature of first-team football as vital in the development of a player.
"All of them were nowhere near our first team but they went out on loan and showed they could swim," Pulis told The Sentinel.
"Some maintain that level and some drop off, I accept that, but you have to get them out there to test them.

"That's why we got him [Cuvelier] out on loan to Walsall in January and he did brilliantly there. But until that point he was struggling in our reserve games.
"It just shows that the quicker we can get them out into league football the better because it either makes or breaks them.
"He's done smashing at Walsall and we will look to get him out again because he doesn't need to be hanging around the reserves.
"Wherever he goes, he needs to be involved; he needs to be at the cutting edge."
