Hoffenheim have completed the signing of teenager Michael Gregoritsch from Austrian top-flight outfit Kapfenberger SV for an undisclosed fee.
The 17-year-old attacking midfielder, who can also play as a striker, has signed a four-year contract, but will spend next season on loan back at Kapfenberger.
Hoffenheim general manager Ernst Tanner is also considering further arrivals and is monitoring Kaizer Chiefs striker Knowledge Musona after being made aware that he was available.
Tanner told Rhein-Neckar-Zeitung: "We have become aware of Knowledge Musona.
"I have been trying to fly over to South Africa to see him in action, however, it did not really work out."
In addition, Hoffenheim have agreed to loan goalkeeper Jens Grahl to second-tier outfit SC Paderborn 07 next season.
