Younis, 37, also insisted that he could still play one-day cricket and contribute to the team. Younis said he wanted to end his cricket career in the role of captain.
"If I get a chance to lead the Test team I will definitely accept the challenge once again," Younis said.
Younis, who has scored the most Test centuries for Pakistan, was captain in all three formats in 2009 before an internal players revolt led to him stepping down as captain while Pakistan were playing a series against New Zealand in the UAE.
Younis said he had always felt that captaincy was a big honour for any senior player and he would like to lead the current Test side. He also insisted that it was unfair on part of critics to compare him with current captain Misbah-ul-Haq.

"I should not be compared to Misbah I am more senior and experienced than him. I am also four years younger than him and my style of playing is more aggressive," Younis said.
"If we don't qualify for the Champions Trophy than questions should be asked off the selectors not players."
Younis also called for more consistency and stability in Pakistan cricket.
Younis was the toast of the nation earlier this month after leading Pakistan to a record breaking win over Sri Lanka in the third Test in which he scored a memorable second innings 171 not out.
