Bundesliga club Hoffenheim has signed Ghana midfielder Afriyie Acquah from Italian side Parma.
Hoffenheim says the 21-year-old has signed a four-and-a-half year contract.
Acquah is the third addition to the squad in the January transfer period, after Luis Advincula and David Abraham.
Hoffenheim is 16th in the Bundesliga and seeking to avoid relegation.
Hannover 96 can almost plan for next season in the top flight of German football after a 3-2 win at Eintracht Frankfurt gave it plenty of breathing space at the bottom end of the Bundesliga.
