The German club are still hopeful of beating off Liverpool to keep hold of the Norwegian star.
Liverpool started the building process for next season early this week as they confirmed that Cameroonian international Joel Matip would be arriving on a free transfer in the summer from Schalke 04.
Now they have been heavily linked with a move for another talented free agent in the Bundesliga.
Now the player himself has spoken up about his future. He says no decision is imminent, telling Sport Bild:
"I really meant (my future will be sorted in) weeks, not a week. Now my adviser is already currently on holiday, then we'll see. There is no new update."
His sporting director Max Eberl has also been commenting on his future - admitting that if a Premier League team comes knocking then they will be unlikely to keep hold of the player. He told Sport Bild:
"We made him a very, very good offer and I am still optimistic that we can keep Howie.
"When it comes to the money, (against Premier League teams) we have no chance."
Liverpool would be right to go for a player like Nordtveit. The former Arsenal trainee is best used in holding midfield but he can also operate at right-back and in the heart of defence - a versatility that Jurgen Klopp would love to have at his disposal.
