Twenty20 will 'finish' Pakistan cricket - Mohammad Yousuf | Cricket News | Australia v Pakistan 2009/10 | Cricinfo.com
Yousuf isn't really the outspoken type, so this has obviously been heavily on his mind. Its important to note he's not anti-Twenty20, he just wants it to not take over Pakistani cricket.
Its interesting to note he references Pakistan's failure to chase 212 against NZ, the famous game where apparently Younis cracked it.
He also compares the Pakistan system to Australia, South Africa and England... where there is probably a more healthy balance of T20 compared to one day and first class cricket.
