Southampton have completed the signing of Cameroon defender Lucien Mettomo on a short-term contract.
"Lucien has been here on trial and he did well so we've given him a short-term contract," Burley told the club's official website.
"We will work hard to get him fully fit and then he will give us extra cover at the back, where we are quite short with injuries to Darren Powell and Claus Lundekvam.
"He is very experienced and a full international with Cameroon. He's played in different countries as well as in the Premiership with Manchester City.
"He's a strong, dominant centre-half and I'm pleased to have signed him."
