WITH a full squad at his disposal, West Wyalong player-coach Rohan Loudon says there will be no excuses for his side to underperform in Sunday's Group 20 grand final against Waratahs at EW Moore Oval.

The Mallee Men are yet to be beaten this season and have been tagged premiership favourites since midway through the competition rounds.

Loudon said now was the time to justify the label.

"We're fit. That's the main thing," he said.

"I don't know how they (Waratahs) are going, but we haven't got anything to whinge about because we've got a full complement.

"We were ordinary at training the other night, but sometimes that's a good sign.

"I'll know more late in the week, but we know how to win.

"We just have to make sure we get it done."

In their streak of 17 wins, the Mallee Men were pushed hardest by Waratahs in round 17 before registering a 24-22 victory.

Loudon said the Tigers had attacking players capable of worrying any team.

"They (Waratahs) can score points from anywhere. They're a good side, don't worry about that," he said.

"They've got a fairly big pack, so we'll try to move them around.

"We'll probably play fairly conservative at the start, but we'll try to move the ball a bit at the same time.

"It's going to be a big occasion. There's a bit nervous energy about, with blokes not saying much.

"But we'll be ready."

Waratahs are also eager for Sunday to arrive. Club president Ken Wells isn't surprised the Tigers have made it this far.

"I was confident once we signed (player-coach) Kosi (Lelei), Moahoni Leleli, Mike (Ioapo) and Johnny (Teleaga)," he said.

"To be honest, I didn't realise how good a footballer Johnny was until we got him on the paddock.

"But I always thought we'd make the top three. If you can do that, anything can happen."

Wells said it didn't bother the Tigers they would start the underdogs.

"I think it's 50-50," he said.

"West Wyalong are unbeaten and are the raging favourites, but we've got a good side.

"We're pretty even right across the park. We've got strong forwards and good backs."

Wells said the Waratahs were also looking to the history books for inspiration.

In 1968, a then unbeaten Tigers were rolled by West Wyalong in the grand final.

"Hopefully we can get them back for that one," Wells said.
