The goalkeeper is excited about the prospect of potentially becoming the oldest Mannschaft debutant of all time in November's friendly internationals
Despite being a regular between the sticks for Die Schwarzgelben, the 33-year-old shot-stopper had never before been brought into the national team set-up until Friday's announcement ahead of the friendlies with England and Italy.
Weidenfeller could replace Toni Turek as the oldest German debutant of all time if he plays a part in either November clash and he expressed his delight at being named in Joachim's Low's 24-man squad.
"I am pleased and happy with this invitation," the Dortmund No.1 told SID. "It's a dream come true.
"I am looking forward to be there in the national team and I hope a cap comes to me in time."
Germany coach Joachim Low believes Weidenfeller deserved to be called up to the squad, but he insisted that Bayern Munich goalkeeper Manuel Neuer remains his first choice.
"We have noted his consistently strong performances for Borussia Dortmund in the Bundesliga and the Champions League," he told the DFB website on Friday.
"We look forward to getting to know him better now. [However] Manuel Neuer is currently our clear No.1."
