According to Bild, the price for Albert Grønbæk is 5 million euros (37 million kroner) if Hamburger SV buys the Danish player from Rennes. Albert Grønbæk said that HSV is a big club with fantastic fans and that he is really happy about the move. Grønbæk also stated it is a good opportunity for him. He added that after good talks with sports director Claus Costa and head coach Merlin Polzin, he can clearly see how he fits into the club's system.

During the winter transfer window, Rennes officially loaned Albert Grønbæk to Hambourg, which is currently 14th in the Bundesliga, with a purchase option included in the deal. This loan follows a previous unconvincing loan spell for Grønbæk at Genoa earlier in the season.

According to Bold.dk, Albert Grønbæk has been presented at Hamburger SV, having completed a loan move from Rennes. The Danish player is being loaned for the rest of the season. Grønbæk expressed happiness about the move and mentioned having good talks with sports director Claus Costa and head coach Merlin Polzin.

According to Hamburger SV coach Merlin Polzin, the club is near to signing Albert Grønbæk, who is under contract with Rennes until 2029. Polzin acknowledged that the player had been seen in Hamburg and that this was not a secret. He expressed optimism about a deal being reached that would provide more offensive options. Grønbæk has been on loan at Genoa for the last six months, where his playing time amounted to 226 minutes. Polzin also stated that he is anticipating getting to know the player but advised that they should wait until all aspects are finalized.
