Swansea City goalkeeper Erwin Mulder has rejoined Dutch top-flight club Heerenveen on a two-year deal.
Mulder, 31, was a free agent after his Swansea contract expired and was not offered a new deal by Steve Cooper.
The Dutchman spent two years at Heerenveen before joining Swansea on a free in 2017.
He played 33 games for the Swans, and finished 2019-20 in the side following an injury to Freddie Woodman.
Woodman had been Cooper's first choice having joined on a year-long loan from Newcastle in August 2019, and Swansea are keen to re-sign the former England Under-21 keeper next season.
Highly-rated youngster Steven Benda will rejoin the Swansea squad in 2020-21 after spending last term on loan at Swindon.
Mulder is the first of Swansea's five out-of-contract players - the others are Kyle Naughton, Mike van der Hoorn, Wayne Routledge and Nathan Dyer - to confirm he is leaving the club.
