Nottingham Forest has parted ways with head coach Vitor Pereira after a short term tenure at the City Ground, The Premier League club said on Thursday.
The Portuguese, who took over from Sean Dyche in February, guided the struggling side to Premier League safety and a run to the Europa League semi-finals.
British media reports have suggested Oliver Glasner is poised to take over at the City Ground following his departure from Premier League rivals Crystal Palace at the end of last season.
"Today marks the end of my journey as head coach of Nottingham Forest," said Pereira in a statement. "I want to say a sincere thank you to everyone connected with this incredible football club.
"Although this decision came as a complete surprise to me and without any warning, I fully respect the club's right to make the decisions it believes are best for its future."
The 57-year-old added: "Naturally, I am disappointed and saddened. I truly believed in what we were building together, and I leave with a sense of pride in everything we achieved over the past months.
"Together, we enjoyed a memorable end to the season. We secured the club's Premier League status, reached the semi-finals of the Europa League, and created moments that will stay with me forever.
"Most importantly, I saw a group of players grow in confidence, belief and togetherness."
Pereira, who thanked his staff, players and fans for their support, insisted he wished the club every success in the future.
"I leave Nottingham Forest with no bitterness or resentment -- only respect, gratitude and wonderful memories."
