The 30-year-old, who is on the books at Reading and also previously played for Arsenal and Hull City, has joined the United States team on a long-term loan until January 2020, occupying an international spot on their roster (official Minnesota website).
Mannone joined the Stadium of Light outfit in July 2013 from the Gunners and made 80 appearances for the Wearside outfit in all competitions, keeping 22 clean sheets, according to Transfermarkt, and left in July 2017 for the Madejski Stadium.
The Italian has played 47 times for the Royals but has made only six starts this term, falling behind Arsenal loanee Emiliano Martinez, Sam Walker and Anssi Jaakkola in the goalkeeping pecking order.
Lyden-Smith took to Twitter as he wished Mannone - described by him as "one of most passionate and hardworking footballers that I’ve ever met" - well as he and his partner embark on their "American adventure":
