... he gets his Premier League wish as Southampton continue to strengthen after a summer of departures.
England internationals Luke Shaw, Rickie Lambert and Adam Lallana were among those to leave for pastures new, leading to the term 'meltdown' being bandied around.
However, those exits have swelled the coffers and Saints made Forster their fifth summer signing on Saturday, with the Celtic goalkeeper moving for a fee understood to be in the region of £10million.
The 26-year-old has penned a four-year deal at St Mary's, where he will compete with Artur Boruc - another former Bhoys goalkeeper - for the number one spot.
Southampton manager Ronald Koeman: "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 Dave Watson before 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."
