Talking about CSK's bowling, former India opener Virender Sehwag expressed concern over the MS Dhoni-led side bowling too many extra deliveries in their matches. "Dhoni has said it before...he wants bowlers to reduce the number of no-balls and wides...It shouldn't go to a stage where Dhoni gets banned," said Sehwag. CSK conceded 11 runs in extras against RCB yesterday.
