Nigel Adkins insists he will go after more defensive reinforcements this summer in order to put together a competitive Southampton squad.
The Saints are back in the Premier League for the first time since 2005 and Adkins says he needs to find a back-up goalkeeper and some defenders to replace the retiring Radhi Jaidi and injured Dan Seaborne.
"We're going to improve the group," he said.
"It is fair to say we are going to need to bring another goalkeeper in as Bartosz [Bialkowski] did ever so well for us but didn't play enough games.
"We've allowed him to move on to Notts County and I am sure he will have a great career up there. We will bring another one if not two goalkeepers into the fold.
"From a defensive point of view, as part of the development we have got we want to bring 50 per cent of the youngsters through the youth team structure.
"Aaron Martin, who has waited patiently on the bench, has gone to Crystal Palace for a half season or full season of games to aid his development.
"With Radhi Jaidi retiring and the uncertainty over Dan Seaborne coming back, we will be bringing another one if not two centre-halves into the football club to keep improving."
