Low left out midfielder Gotze, who scored the winning goal in the final against Argentina four years ago but has had a lacklustre season.
The 32-year-old Neuer suffered a broken bone in his foot and only returned to training days ago but Germany coach Joachim Loew made a decision to take 4 keepers to the training camp in the Italian Alps from May 23-June 5.
Remembering that he first walked through the doors of Italy's Coverciano training camp in 1978 with the under-14 team, Mancini said it was the right moment in his career to take on the challenge of coaching his country. "He is a great player but he wasn't in form", Leow said. Loew opts for Petersen over Bayern Munich forward Sandro Wagner.
The title-holders will have to submit their final 23-man squad including three goalkeepers on June 4. Uncapped Freiburg striker Nils Petersen received an invitation from the national team after scoring 15 goals in the Bundesliga this season. "And apart from that he is a very good substitute", Loew said of Petersen.
The 2014 champions who disgraced Brazil 7-1 at the semi final stage before overcoming Argentina 1-0 in extra time have kept faith with injured Manuel Neuer, despite their first choice goalkeeper being out with a broken foot since September past year.
"It wasn't his best season".
Manchester City's Leroy Sane and Ilkay Gundogan are among the Premier League players to be selected. "Some (of the reaction) seems to be over the top to me".
After the Federation Internationale de Football Association deadline, a player can only be replaced if he seriously injures himself 24 hours before the team's first World Cup match.
