The 22-year old centre-back is going from strength to strength in Scotland since his £2million summer move and Lennon feels he has unearthed a gem who could still easily be playing in Holland's Eredivisie.
"The Dutch are usually very proficient at spotting talents and signing them," he said ahead of Wednesday's Champions League meeting with Ajax.
"I don't know why they didn't move for Virgil.
"He looks languid at times, he maybe has a lackadaisical style, but when he turns through the gears he's very quick and powerful.
"When I first saw him I thought 'Wow'. He looked a really good player. At first you wonder if there's something you're missing.
"But I knew we had to keep a watch on him. We watched him against Ajax and Johan Mjallby came back and said he'd played well, that he rated him.
"So, I don't know why the bigger clubs there didn't move for him.
"Having been over to Holland to watch Ajax, and speaking to a few scouts, they were surprised a club in England or some of the bigger sides in Holland didn't buy him."
