Alex McCarthy has displaced Fraser Forster as first-choice Southampton keeper with two clean sheets in three matches.
But Saints are without a league win since November as they prepare to face out-of-form Watford on Saturday.
"As the games go by, the players are picking up confidence," McCarthy told BBC Radio Solent. "We're working hard to get ourselves out of this position."
A spell of injuries since his move to St Mary's in August 2016 have limited his chances to cup competitions.
"The medical staff have been excellent here," he revealed. "I'm also close to my family, which has help focus the mind and keep my head down.
"It's frustrating being injured, but it's such a reward when you get back out there playing."
