Cedric Soares has resumed full training to give Southampton a fully-fit squad.
Leicester City have also welcomed Robert Huth and Matty James back to training, although the pair are unlikely to return to first-team action just yet.
Did you know?
Southampton have lost only one of their 11 Premier League home matches against Leicester City (W5 D5), and that loss was at the Dell in April 2000 (1-2)
Charlie Austin has scored eight goals in his last 11 Premier League matches for Southampton. Since the start of 2014/15, only five Englishmen have scored more PL goals than his 30.
Dusan Tadic provided his 26th PL assist for Southampton in Sunday’s 1-1 draw with Arsenal. Only Matt Le Tissier (64) has more for the club.
Riyad Mahrez has been directly involved in eight goals in 16 PL appearances this season (four goals and four assists), just one fewer than in 36 matches last season (six goals, three assists).
What the managers say
Mauricio Pellegrino: "Charlie Austin's goals are a consequence of his excellent preparation. As a group, together we are approaching full strength."
Claude Puel: "It will be a strange feeling, of course, to go back to St. Mary’s Stadium. The most important thing for us is to keep a good focus.”
