After finalising his move to the City Ground, he told Forest's website: "I'm absolutely delighted to be joining such a fantastic club with an amazing set of fans and a wonderful history.
"I'm really excited to work with everyone at the club from the manager, players and goalkeeper coach Danny Alcock.
"The conversations with the manager have been outstanding. When I spoke to him, he was great and made me feel loved and I can't wait to play under him.
"Seeing what it's like around this place, I feel like the momentum is with us, so we've just got to build on it, stick together and go again.
“Finally, just a massive thank you to the fans for the welcome I have received and I can't wait to celebrate some brilliant moments together this coming season."
