Vermijl, 22, arrived at United from Standard Liege back in 2010, but has made just one appearance for the Red Devils, and in a bid to accelerate his development, he was sent out on loan to NEC Nijmegen in Holland by new United boss Moyes.
The Belgian Under-21 international has impressed during his stint in the Eredivisie, scoring three goals in 21 games from right back, raising questions about whether he could make a bid to play first-team football under Moyes next season, with a squad overhaul set to commence in the summer.
But agent Tony Dullers suggests that the future of his client depends almost entirely on the future of under-fire boss Moyes, who has endured a difficult first season at Old Trafford since replacing the legendary Sir Alex Ferguson last summer, and with just over a year to run on Vermijl's contract, Dullers suggests he could leave unless Moyes goes.
"He is under contract at Manchester United until June 2015 but much will depend on the situation of David Moyes. If the manager stays, then it does not look good because he let Marnick go quite easily to NEC. If Moyes is sacked, it may open greater chances (at United)," Dullers said.
"At Manchester United, they are very happy with his development. They want Marnick to work at a better club next season but another loan is not ideal. He will either get his chance in the first team, or move on permanently."
After beating Olympiacos 3-0 last night, it seems United are unlikely to part ways with Moyes for the time being, but his first signing at the club last summer was Uruguayan right back Guillermo Varela - who is probably ahead of Vermijl in the pecking order, leaving the Belgian to consider his future at the club.
