Bayern are the only unbeaten side in the Bundesliga this season following a magnificent start under new boss Vincent Kompany.
The Bavarians' winning streak ended on Saturday with a 1-1 draw against champions Bayern Leverkusen at the Allianz Arena.
Neuer says their success on the pitch so far this term has been down to 'sticking to our style', something he suggests they didn't do under Tuchel last season.
'We have that confidence back again. No matter which team we're playing against, even against Leverkusen,' the veteran goalkeeper said.

'We're sticking to our style, we've been dominant. That's something different than before.
'The security that Kompany gives each individual is noticeable on the pitch, the connection we have. We play as a team!'
Bayern Munich endured a difficult campaign last season, finishing third in the Bundesliga table and 18 points adrift of Leverkusen.
Ther German giants were also knocked out of the Champions League by eventual winners Real Madrid in the semi-final stage.
Bayern and Tuchel had already agreed to 'mutually end our collaboration' following 'an open, good conversation' in February.
Under Kompany's guidance so far, they have won six of their seven games across all competitions so far including a 5-0 win over Werder Bremen and a 9-2 victory against Dinamo Zagreb in the Champions League.
Bayern will sekk to extend their unbeaten start when they travel to Aston Villa on Wednesday to face Aston Villa.
