The Magpies are long-time admirers of the French international, but their attempts were halted in the summer by Bayer Leverkusen’s £60m asking price for the player.
They have not given up on their interest though and are likely to knock at the door of the German side yet again.
Leverkusen however will not willingly cooperate on selling Diaby soon as they are keen to keep him at the club.
Rolfes knows that Diaby is a wanted man, but insists no offers have yet arrived.
“For sure, we want to keep Moussa for as long as possible”, Rolfes told the Daily Express.
“I know a lot of scouts have been sitting on our tribune during our matches because we have a lot of interesting, exciting young players with high potential.
“So, it’s the same as [Patrik] Schick [also a Newcastle United target].
“We did not receive any offers for him but we are not even looking for that at the moment.
“We wanted to keep him and play Champions League football with him this season.”
The French international has already made six goal contributions in 13 appearances for Bayer Leverkusen this season.
