Aaron Woods maintains Leichhardt Oval will always be home and has told his Sharks teammates they're "absolutely kidding themselves" if they fail to make the finals in Paul Gallen's last year.

The Cronulla prop will wear his usual game-day underwear - emblazoned with Leichhardt's postcode across the back - for his first return to the Wests Tigers' spiritual home in a winner-takes-all top-eight shootout with his old club on Sunday.

It will represent an emotional homecoming for the 28-year-old, who hasn't played at the ground since leaving the Tigers two years ago before a brief stint at the Bulldogs, where he was squeezed out due to salary cap pressure.

But after Canberra No.7 Aiden Sezer potted three field goals to condemn the Sharks to a daunting trip to a sold-out Leichhardt to book their finals spot, Woods has spoken of his affection for his junior club and the ground which will farewell Robbie Farah.
