The 23-year-old believes that his counterpart is an excellent shot stopper, but feels he will soon be overtaken by other keepers in the Bundesliga
The Germany international has won universal plaudits since his arrival at the Allianz Arena, but the 23-year-old believes that Neuer will soon be outshone by the wealth of young goalkeepers in the Bundesliga.
"It is undisputed that Neuer is excellent, a complete goalkeeper and is the number one [in Germany]," Kraft told Kicker.
"I don't yet see him as an absolute world-class goalkeeper. The others will improve and at some point will reach his level."
Neuer's arrival at the Bavarian outfit marked the end of Kraft's seven-year spell at the club he joined as a teenager, but the former Germany youth international says he is enjoying being a senior player in the German capital.
"In Munich, I was always the kid who came from the youth ranks. In Berlin, I see myself as a leader in the team, a role which I enjoy."
Hertha Berlin ended the first half of the Bundesliga season in 11th place and will restart their campaign with a trip to relegation candidates Nurnberg.
