The 36-year-old has played 27 Tests, 91 ODIs and 36 T20Is for Pakistan with 237 wickets across formats.
"I have not given up hope of playing in the World T20 this year and I think senior players as long as they are fit and performing should be considered for selection," he said.
Wahab is still not sure what "issues" do selectors have with senior players.
"I don't know exactly what issue people have with senior players. Perhaps youngsters listen to what is told to them, while seniors always have their own say in matters and you have to convince them," he said.
The current selection committee headed by Muhammad Wasim and head coach, Misbah-ul-Haq have since last year ignored senior players like Wahab, Muhammad Amir and Shoaib Malik and also dropped another senior, Imad Wasim for successive series but have recalled him for the T20 matches in England and West Indies.
