The 20-year-old Argentinian has been found wanting on several occasions this season and was embarrassingly caught out last night as Norwich held Saints to a 1-1 draw at St Mary's.
"Likewise it could have been less if he hadn't made the saves against Newcastle and other relevant saves in other games," Adkins said in Gazzaniga's defence.
"Listen, he is a young goalkeeper. Situations are going to be highlighted if we don't keep clean sheets, he doesn't make saves, doesn't kick the ball right, doesn't catch it.
"They just get highlighted and magnified even more so, but we've got to have confidence in the young man.
"We believe he is going to the very, very top and I have certainly got a lot of confidence in him."
