The 23-year-old scored his first league goal for the club in last Saturday's 4-0 win against Rushden & Diamonds.
That came three days after knocking Rotherham out of the FA Cup - and they made it three wins on the trot against Southport 2-0 on Tuesday night.
"We've a fantastic squad. There's a nucleus here to push on," said Racchi.
"Without a doubt, we're going to Darlington to win.
"Obviously big teams come into the competition in the third round. And, if we can win on Saturday, it doesn't really matter who we get.
"If we get another low team it's another chance for us to progress even further and if it's a chance to go to Old Trafford or Stamford Bridge, then what an experience for the lads!"
