Dailly has impressed George Burley during his loan period

The Scotland international was drafted in by Saints boss George Burley in September to ease his defensive crisis.

Dailly, 34, has impressed in a patched-up back line, not least during Sunday's 1-0 home win over Cardiff.

Burley said: "We brought him in for a month as we had other players coming back from injury, but we have lost more players and we are short of numbers."
