Vaibhav Sooryavanshi has scored 404 runs with a strike-rate of 237.64 at this year's IPL

Few have had a better view of the development of cricket's 15-year-old sensation Vaibhav Sooryavanshi than former England all-rounder Mike Yardy.

Yardy was in the opposing dugout when Sooryavanshi, then aged 12, played for India against England in an under-19 series.

He was coach once more when the precocious left-hander toured England last summer - Sooryavanshi scored 143 in the fourth 50-over match in Worcester - and again when the teenager hammered an incredible 175 from 80 balls against England in the Under-19 World Cup final in February.

So, has he spotted a weakness?
