Wolves have signed Hungary midfielder Denes Rosa on an initial deal which will run until the end of the season.
Rosa has won nine international caps for Hungary
Rosa, 28, will not be eligible to play until the turn of the year, assuming he gains international clearance.
Wolves will pay a nominal fee to Ferencvaros as Rosa's contract was
due to expire in the summer.
Rosa, who joined Wolves on trial earlier this month, has signed a six-month contract, although Wolves have the option of extending the deal.
