Diamonds ended a six-game run without a win with a 4-1 success over Aylesbury United at the weekend.
That victory ensured Diamonds remain in control of their own destiny as they sit in the second automatic promotion place in the Evo-Stik South League East behind current leaders Beaconsfield Town.
But a win over fifth-placed AFC Dunstable this evening will send Peaks’ team back to the top and, more importantly, five points clear of third-placed Hayes & Yeading United.
It really is crunch time for Diamonds in their bid to move up to Step Three.
And boss Peaks said: “It’s a massive game against a good team.
“I have watched them a few times this season and they have some good players, we will have to be at our best to get what we want.
“I am sure the win at the weekend will have given us a boost in confidence.
“From my point of view, I have never lost the belief because we have good players and that never goes away.
“We had a little run without a win but the result on Saturday has given us that momentum.
“The fact is that after four draws and a win, we are unbeaten in five and on a nice little run.
“Even when things haven’t been going for us, we have still been picking up points and hopefully they will prove to be important at the end of the season.”
