Southampton have completed the £2.1m signing of Nigel Quashie from south coast rivals Portsmouth.
The 26-year-old midfielder, who was captain at Fratton Park, has signed a three-and-a-half year deal.
Quashie told Saints website: "It's a big move for me and I am happy to be linking up with Harry Redknapp again.
"I am certain we will stay up - I would not have come here if I had any doubts about that, but we need to get a few results quickly," he added.
Southampton chairman Rupert Lowe said: "Harry really wanted Nigel - he thinks he is a strong character who will add to the dressing room.
"We are delighted to make him our third signing since Harry arrived."
