The youngster has caught the eye of the Champions League quarter-finalists with a transfer deal being lined up, however Saints will keep the teenager as long as they can, Robonson insisted.
Their hand may be forced though Robinson admitted in light of interest from one of European football’s big names.
Robinson said: “Dylan is certainly still our player and will remain so until someone tells me different.
“We’re at the mercy of the bigger clubs unfortunately. That’s the way of the world and they buy them younger and younger.
“They buy boys at 14, 15, 16 and we’re not in control of that. All we can do is try and bring them on.”
Reid also spent time on loan with Queen’s Park making two appearances.
Robinson hopes he can stay in Scotland longer to develop but the interest highlights the work being down by the Buddies in bringing on players including the Scotland under-17 who will be in Israel with the national team later this month for this summer’s European Championships which kick off against Denmark on May 17.
