Manchester United signed Turkey goalkeeper Altay Bayindir from Fenerbahce on Friday in a deal worth a reported £4.3 million ($5.3 million).
Bayindir agreed a four-year contract with the Premier League club, who have the option of a further 12 month extension.
The 25-year-old, who has been capped five times by his country, joins on a four-year contract.
Last season he was a key player for Fenerbahce as they won the Turkish Cup and finished second in the Super Lig.
“It is a huge honour to join Manchester United and become the first Turkish player to represent this incredible club,” said Bayindir.
“I have a passion for success, and I will give everything to help this special group of players to achieve our ambitions.
“I cannot wait to start working with such an experienced goalkeeping unit. We will support each other and drive high standards every day so that each of us is ready to perform whenever called upon.”
Bayindir has made 166 appearances in his career, with 53 clean-sheets.
He joined Fenerbahce from Ankaragucu in 2019 and was a key player last season as they won the Turkish Cup and finished second in the Super Lig.
“Altay is an excellent addition to our squad and adds further quality to our already strong group of experienced goalkeepers,” Manchester United Football Director John Murtough said.
