Melbourne Victory striker Archie Thompson has labeled Friday night's Round 21 clash against Wellington Phoenix as the biggest of the season.

The Victory have plenty riding on the last regular match of the season and Thompson understands the importance of it.

"I would have to say personally it's probably the biggest game of the season," Thompson said.

"It's deciding a minor premiership, it's deciding a top-two spot - it's deciding an Asian Champions League spot.

"I can't say any more about it, it's the hugest game of the season."
