United will pay Newcastle a loan fee of £2 million and also have an option to make the deal permanent at the end of the season. There is an obligation to sign him permanently at £6m if Dubravka starts a certain number of Premier League games.
"I'd like to sincerely thank everyone at Newcastle United, and especially the fans, for many great experiences over the past four and a half years. I enjoyed every minute of my time there and made amazing memories to look back on. My focus is now on helping Manchester United, and we'll see what the future holds after I have given my all this season. I am excited to be here!"
