Southampton have announced the signing of goalkeeper Fraser Forster from Celtic for an undisclosed fee.
Forster, who was part of England's World Cup squad, has signed a four-year contract at St Mary's.
Saints boss Ronald Koeman told the club's official website: "Fraser is a very talented player and we are delighted to be able to bring him to Southampton. This is another important part of our rebuilding process ahead of the start of the season.
"The fact that he has worked with [Southampton's senior goalkeeping coach] Dave Watson before [for England] means we already know all about his strengths and weaknesses, and I am confident that we will be able to help him improve even further.
"Fraser is the perfect fit to help complement the players we already have, and he will add a lot of quality to the squad. He is an exciting English player with a very good reputation within the game and, at 26, he will enjoy the best years of his career at Southampton."
Sources have told ESPN FC that Saints goalkeeper Artur Boruc is likely to leave the club following Forster's arrival.
Forster joined Celtic from Newcastle United on a permanent deal in 2010 after having spent the previous two seasons on loan at Parkhead.
The 26-year-old won three Scottish Premier League titles and two Scottish Cups during his time with the Bhoys.
