Did you notice the small similarity between Steve Smith and PV Sindhu on Sunday? Arms aloft and then over her face. Sindhu stood drained, exhausted and relieved at the centre of the court for few seconds, just like Smith after his 24th Test ton at Edgbaston earlier this month. And understandably so. It was a battle that lasted for three long years and not for 37 minutes which the scoreboard showed. This gold was long in the making and Sindhu had nothing left.
