The defender moved to Molineux in 2017 and went on to make six senior appearances after heading home a late equaliser on his debut to earn Wolves a crucial point against Hull City in the Championship-winning season.
Since then, the 23-year-old has been a regular for the under-23s while making occasional outings for the first-team, featuring in the Premier League, FA Cup, League Cup and Europa League, before a spell on loan at Grasshopper Club Zurich.
Everyone at Wolves would like to thank Oskar for his efforts in gold and black and wish him well for the future.
