Western Sydney Wanderers striker Mark Bridge has been on a self-imposed drinking ban all season but he is set to pop the cork at the stroke of full-time in Sunday's A-League grand final to celebrate the end of a fruitful season.

The former Sydney FC striker rediscovered his form out west, and credits his rise to becoming the club's leading goal scorer to one change in his approach. ''If I could say one word, it would be discipline,'' Bridge said.

His relationship with alcohol was never problematic but Bridge embarked on a season-long booze ban to limit any potential off-field distractions in hope of returning to the scintillating form that won him a title with the Sky Blues. He said it was slight lifestyle alterations such as one or two post-match beers that could have a small yet significant effect on his performances.

''Doing it [drinking] at the wrong time doesn't help your recovery, it doesn't help you become better. It's a snowball effect; you do it once and you're behind the eight-ball and catching up all year,'' Bridge said. ''I've been very good this year, I haven't had one sip of alcohol at all, but come grand final night, when we win the game, I'll definitely be having champagne or a beer or two.''

Sunday's grand final showdown against the Central Coast Mariners will be the 27-year-old Bridge's third A-League decider.
