Wolves have re-signed Republic of Ireland full-back Matt Doherty on a three-year contract.
The 31-year-old featured just twice for Atletico and returns to Molineux as a free agent.
He played 302 times for Wolves during his first stint between 2010 and 2020, scoring 28 goals.
The Republic of Ireland international featured in every Premier League game of Wolves' 2018-19 campaign and helped Nuno Espirito Santo's side to back-to-back seventh-place finishes after they sealed promotion from the Championship.
Doherty was part of the Wolves team that reached the quarter-finals of the Europa League in 2019-20.
The defender becomes Wolves' seventh signing of the summer as Julen Lopetegui looks to reshape his squad after finishing 13th in the Premier League last season.
