The Bayern Munich goalkeeper is of the opinion that his old rival for a place in the DFB Eleven could be in line for a return to die Mannschaft if he keeps up his form
The former Leverkusen man has enjoyed a fine start to his career at the Imtech Arena, and impressed once again last Saturday, when he made a string of brilliant saves as Thorsten Fink's men claimed a 1-0 win over Hannover.
Neuer believes his old foe for a place between the sticks for Germany has all the qualities necessary to play for Die Mannschaft.
"I think that Andreas Kopke [Germany's goalkeeping coach] and Joachim Low are watching him," Neuer told Bild.
"He has shown some very good performances this season, but it remains the decision of the authorities. I trust Rene can make the step up to the national team."
When asked if Adler's performances were what he expected, Neuer said: "You never know what he can do. When Rene is fit, he is a very good goalkeeper."
