Derbyshire batsman Wayne Madsen is adamant his side can still qualify for the FL t20 quarter-finals despite their 10-wicket hammering against Lancashire.
The Falcons may now have to win their last four games to make the top four in their group and progress.
But Madsen told BBC Radio Derby: "We do believe and we have to believe. We have played good one-day cricket and if we can get on a run we can do it.
"Three wins may be enough but we will be looking to win our last four."
Derbyshire, who are sixth in the North Group, face tricky away fixtures against Warwickshire on Wednesday and Leicestershire on Friday but Madsen is remaining positive.
"We have an uphill battle to qualify and we have to get on with it," he said.
"We have to get a win over both those teams and we just have to be positive about it."
And he said it is vital the team do not dwell on their humiliation against Lancashire.
"You get that in a season where you get a game where it just doesn't click," the South African-born opener added.
"You have to sometimes put it down as a bad day at the office and you have to almost forget about it and move on to the next one. We cannot look back at a game like that."
