A 1-1 draw against Mainz in Babbel's first home game since replacing Holger Stanislawski preserved his unbeaten record, but he feels a bit more time is needed before the players perform the way in which he wants them to.
"We were unable to use the chances we created after going 1-0 up and the team is still struggling - they are not yet liberated," he said after Friday's game.
"The players are clearly still thinking too much and we have got to work on getting more self-confident.
"I was happier with the second half when we were superior."
Mainz coach Thomas Tuchel was disappointed with the draw, saying his side is not picking up as many points as they deserve following their third straight 1-1.
"The own goal is just typical for our whole season," he is quoted as saying on Kicker.de.
"It costs us a huge amount of points, and nerves. We are a hard team to play when we go away and we have proven that again, which is positive.
"We have earned too little for the efforts we put into every game."
