The Lions pulled off something of a surprise when the 35-year-old former Aberdeen and Scotland forward ended his Norwegian exile by signing in August and he has gone on to notch 13 times this term, one behind Middlesbrough-bound Andrew Halliday.
Winters, voted the club's Players' Player of the Year, has been rested since the club clinched the Third Division title, and De Vita, who has scored 11 goals himself, said: "The guy who has made a huge difference is Robbie Winters. From the start, I think he carried the team a few times when we a were struggling. He's the one that really made the difference for us, in the early games especially."
Livi boss Gary Bollan, meanwhile, is leading the chase for Dundee goalkeeper Tony Bullock after releasing 35-year-old Roddy McKenzie.
Bollan has given first-team reserve Craig McDowell a start since clinching the title and Under-19 keeper Darren Jamieson played in Tuesday's 2-0 victory against Albion Rovers. However, both McDowell, who is 20, and Jamieson lack the experience Bollan believes is necessary for an assault on the Second Division next year. Bullock, who is 38, would provide that, allowing the other keepers to continue their progression.
Stirling Albion striker Ian Russell has also been linked with the Lions. The 27-year-old has scored eight times for the Binos this season and once for Alloa. Livi defenders Danny Griffin and Jason Talbot have also been released.
East Stirlingshire are the opponents tomorrow at Almondvale, and, after the game
Livi fans are invited to a Championship party starting at 7pm with a disco going on to 1am. Entry is free and it is open to all.
