Callejon believes his side are now moving in the right direction following a disappointing first half of the season.
"In the last few games we've been feeling better. Now we have to continue like that," said Callejon ahead of Saturday's trip to struggling Granada.
"For us the result in the Barca game is good. We didn't want to let in any goals, but the draw isn't bad. We're confident of doing well at the Nou Camp."
