Nottingham Forest have appointed former Crystal Palace manager Oliver Glasner as their fifth head coach in less than a year.
The Austrian arrives at the City Ground as a replacement for Vitor Pereira, who was sacked on Tuesday - two minutes before an exit clause in his contract was due to expire.
"Oliver is a winner," said Forest owner Evangelos Marinakis.
"It was clear that we share the same vision, the same ambition and the same relentless desire to succeed."
Contact with 51-year-old Glasner, who left Palace at the end of last season, was initiated earlier this summer.
Nuno Espirito Santo began last season as Forest manager, while Ange Postecoglou, Sean Dyche and Pereira have had a spell in charge since September.
Glasner became Palace boss in 2024 and led them to their first major honour in his first season - the FA Cup - before winning the Europa Conference League last season.
They won the Community Shield in August, beating Liverpool on penalties.
Glasner said in January he would leave Palace because he wanted a new challenge, despite being offered a new contract.
On joining Forest, Glasner said: "From my very first conversations with the owner and the leadership team, it was evident to me that they have a clear vision for this football club and complete trust and belief in me and my staff to build a strong future together over the long term.
"That trust and shared commitment, together with the potential that I see within the squad, were key factors for me and I am excited about what we can achieve together."
Glasner is one of only three coaches to win the Europa League and Conference League, having led Eintracht Frankfurt to victory in the former in 2021-22.
Marinakis said: "He has consistently demonstrated throughout his career that he can build outstanding teams and deliver success against the strongest competition.
"He has earned success through his leadership, his personality and the style of football his teams play.
"It has always been our goal to establish Nottingham Forest once again among the leading clubs in England and Europe.
"Our ambition is not simply to compete - our ambition is to win, to challenge for major honours and to create a football club that our supporters can be proud of for many years to come."
Pereira, who replaced Dyche in February, guided Forest to 16th in the Premier League - five points above the relegation zone - and the Europa League semi-finals, where they lost to eventual winners Aston Villa.
