The on-loan Borussia Monchengladback is desperate to stay long-term on Tyneside.
Though the jury is out, Anita remains convinced that de Jong has plenty to offer the Toon.
"Luuk wants to stay here beyond the end of the season and I hope that happens because he is a very good player," said Anita.
"Unfortunately, chances haven't really fallen for him so far but I'm sure they will in the weeks ahead and he will take them.
"Since he came in January, Luuk has been doing everything he can to prove himself at Newcastle and I believe it would be good for everybody if he signs for us."
