Celtic urge Newcastle, Southampton target Van Dijk to give them "one more year"
"My view is that one year is far too early for him," said Lawwell. "He needs another year in the Champions League.
"I've spoken to Virgil's agent. We don't want to sell him. We have a manager who I think will make him - and all our players - better.
"If I was his advisor, I would be saying: 'Forget this year, let's stay and develop'."
