Darren Randolph has joined Middlesbrough in a £5m move on a four-year contract from West Ham.
The Teesside club announced on Saturday the signing of the Republic of Ireland goalkeeper, following Joe Hart's loan move to the Hammers from Manchester City.
Randolph becomes Boro's ninth addition of the summer following relegation to the Sky Bet Championship.
Boro broke their transfer record last week with the £15m signing of striker Britt Assombalonga from Nottingham Forest.
Randolph made 26 appearances for West Ham last season, often standing in for the injured first-choice Adrian.
The 30-year-old has made 50 appearances for the East London side since joining on a free transfer in 2015 following release from Birmingham City.
The Bray-born 'keeper began his career as a trainee at Charlton, with loan spells at Accrington, Gillingham, Bury and Hereford, before joining Motherwell and then Birmingham in 2013.
After completing a medical and agreeing personal terms, Randolph told the club's official website: "I'm delighted to get it all signed and completed.
"Arriving here and see the facilities, it's definitely a Premier League club.
"I want to come here and get the club back to where it belongs and be part of something special."
