The Championship club have struggled in recent games, picking up just one point in their last three fixtures against Cardiff, who won promotion to the Premier League on Tuesday.
The Hornets face Blackburn Rovers at Vicarage Road on Saturday before meeting Leicester the following week and Leeds on the last day of the season.
"We still have three games left," Pudil told chovanecsports.cz. "We need to get on a run to give us some self-belief before the play-offs. I think Matej (Vydra) will start to score again and his goals always help us.
"I wouldn't use the word 'crisis'. We've had a rather tough draw and we conceded some late goals. I don't know why but we have struggled against some of the weaker teams.
"We've lost the chance to earn out right promotion now, and we would need a miracle for it to happen.
"But we are almost a completely new team, getting to the play-offs in itself is a huge achievement.
"We've sort of coped well with a tough series of matches- we won at Hull, drew with Cardiff and lost our last two. The last one, at Peterborough, went wrong in terms of our performance. For 60 minutes we were terrible."
