Ex-India all-rounder Ravichandran Ashwin said Punjab Kings skipper Shreyas Iyer and head coach Ricky Ponting share a "very good elder-brother, younger-brother kind of relationship". "Shreyas knows that Ricky has his back...it takes a lot of load off him...I think they are a good combination," the 39-year-old added. The duo were earlier together at Delhi Capitals before reuniting at Punjab Kings.
