Fulham have taken up the option to sign on-loan defender Michael Madl from Austrian side Sturm Graz.
The 28-year-old has signed a two-year contract with the Championship side until the summer of 2018.
Madl made 13 appearances and scored one goal after joining the club on loan in January.
"I've enjoyed the past five months with Fulham where the fans have made me feel so welcome from the very first day," Madl told the club website.
"I'm looking forward to a new exciting season in the Championship and I'm confident that I can be part of something special with the club."
