They'll face minor premiers Port United FC at Port Regional Stadium on Saturday in a rematch of their qualifying final two weeks ago.

Port United got the better of them in that encounter and Summers admitted it was in the mid-field where the game was lost - but they've done a lot of work since then.

After focussing on their mid-field in training, Wallis Lake bounced back strongly in last Saturday's final against Port Saints with a comfortable 4-1 win.

"We dominated the mid-field," Summers said.

"The training paid off."

Now he feels his players are hitting their straps at the right time and if they can once again gain the upper hand in the mid-field, the premiership will be theirs.

"I shouldn't be confident because we haven't beaten this team all year," he said.

"But we seem to be peaking at the right time."

He pointed to Mark Mallia, Reece Reynor and Bayden Schumann as players who all had strong games last week, and believed they'd once again play big roles in the grand final.

"They seem to be gelling really well," he said.

"They're linking up with the backs and getting the ball up the front."

Attacking players Mitch Yarnold and Roan Whiteman will also play vital roles, as will Ethan Perry, who Summers sees as one of their strongest assets.

"He's coming into form," he said.

"He's doing a lot of work setting up the other strikers."

Despite the hard work they've put in and the good form they've found, Summers admits they still face a formidable challenge, acknowledging the class of their opponents.

"They're a strong outfit all over the park," he said.

"Their mid-field is outstanding."

Still, he's quietly confident, and that confidence extends to Wallis Lake's reserve grade side, who will be seeking a premiership on the same day against the Macleay Valley Rangers.

Summers believes the side overcame an important litmus test in their 2-0 win over Port United on the weekend and should carry that form forward into the grand final.

He sees the team's two most experienced players, defenders Mark Jones and Mark Fletcher, as crucial to the side's success, along with goal-scoring phenomenon, Jarrod Naylor.

With Fletcher playing his last-ever game for the club, the team will have extra motivation going into the clash to send one of their stalwarts off on a high note.

Interestingly, their coach Chris Cheers' first child is due on the day, which may see him miss the game and Summers step into the role.

In any case, a big week lies ahead for everyone at Wallis Lake.

The reserve grade grand final starts at 12:45pm and first grade kicks off at 3pm.
