Southampton manager Mauricio Pochettino has admitted that he does not know how long goalkeeper Artur Boruc will be sidelined for.

Reports have claimed that the 33-year-old could be out of action for six weeks after fracturing his hand in Sunday's 3-1 defeat to Chelsea.

"It is difficult to analyse how many weeks Artur will be out for," Pochettino said in a press conference.

Argentine goalkeeper Paulo Gazzaniga is expected to play in tomorrow's match against Aston Villa as reserve keeper Kelvin Davis is also injured.
