Shastri reckons that T20 format is not meant for bilateral series between international teams and the slam-bang style of cricket should be restricted to just World Cup. Shastri, one of the most successful India coaches, also feels that franchise cricket together with a biennial T20 World Cup is best way forward when it comes to shortest format, considering fans' appetite for it. Shastri's comments have come, days before India's five-match T20 series against South Africa. "...there's too much of bilateral stuff going on in T20 cricket. I've said that (before), even when I was the coach of India, I could see it happening in front of my eyes," Shastri told ESPNcricinfo.
