Gayle always struggles on pitches where boundary hitting is not easy. He is never comfortable in rotating. Seeing Badree Kohli might have tought Chahal can be dangerous as well but didn't happen that way today. Anyway it is just 10 from 2 overs.
Today might be the day Dhoni fires once more? Although personally I think he's done. Even if he has the odd flourish, his lack of consistency does not justify batting in the upper middle order any more.
