Daghim spent three years at RB Salzburg after moving to Austria as a teenager from Aarhus club AGF. During that time, he also enjoyed a loan spell with feeder club Liefering in 2023/24 before he gained valuable Bundesliga experience with Wolfsburg last season.
"Adam is a young, talented player and, with his skills and tremendous pace, was the obvious choice for the profile we were looking for," explained Hoffenheim sporting director Andreas Schicker. "At just 20 years of age, he has great potential for development and yet can already draw on international experience at club level and with the national team. He is also familiar with the Bundesliga from last season's stint at Wolfsburg."
Daghim made 30 competitive appearances for Wolfsburg, making two goals and contributing one assist as the Volkswagen club suffered relegation from the Bundesliga.
Daghim, who made his senior debut for Denmark earlier this year for Ukraine, has signed a long-term deal. The 20-year-old is expected to make his competitive debut for Hoffenheim in the DFB Cup on 22 August, when his new side travels to third-tier Erzgebirge Aue.
"I'm really looking forward to my time at Hoffenheim. I know what opportunities this club in particular offers young players in terms of development," said Daghim. "That's why I made a very conscious decision to join TSG, and I'm ready to go and quickly find my place in the team here. I want to do everything I can to ensure we're successful together."
