Robins have won four out of five Hellenic Division One East games this season, their only defeat coming to leaders Rayners Lane in the second game of the season when new-look Bracknell were still finding their feet.
"We've had a lot of cup matches which is why we're behind, but I've been stressing how important these league games are," Nebbett told the News.
"We want to win the league. I've won leagues before and I know how important it is to have the right attitude. We're feeling good, we're optimistic."
Robins are due to meet Reading Football League Premier Divison outfit Ashridge Park in the Berks & Bucks Cup at Larges Lane on Saturday (3pm ko).
