Ross Lyon has said he is ready to "give everything" the second time round, after St Kilda's announcement that he is the Saints new coach.
Lyon returned to Moorabbin as senior coach on Monday with a new four-year deal, 11 years after he sensationally left the club for Fremantle.
The 55-year-old will replace Brett Ratten, who was sacked less than a fortnight ago, despite signing a two-year contract extension just months earlier.
