Former England captain Nasser Hussain trolled his fellow Sky Sports commentator Dinesh Karthik over a microphone blunder on Day 4 of the fourth Test at Old Trafford in Manchester. Hussain hilariously reminded the former Indian keeper-batter that the microphone is equally important, especially now that he is new to the commentary gig.Karthik, who played for India in all three formats, made his debut for Sky Sports as a commentator during The Hundred in 2021. He was also part of the on-ground commentary panel for the World Test Championship (WTC) held in England the same year. Karthik was also one of the commentators in the WTC final this year.Meanwhile, Hussain said in a video shared by Sky Sports:"Dinesh Karthik, it's been a long day and you are new to this commentary gig. But I'd say your microphone is equally important. This happened at tea.The video below shows Karthik forgetting his microphone while speaking to Ian Ward on air:The 57-year-old didn't forget to take a cheeky jibe at Michael Atherton either and reminded him of an old incident by claiming:"Don't worry, happens to the best. Michael Atherton, he once tried to commentate using a coffee cup."Karthik announced his retirement from all forms of cricket in 2024. He took up the role of the batting coach for the Royal Challengers Bengaluru (RCB) ahead of IPL 2025.England kept at bay ahead of Day 5 of Manchester Test vs Team IndiaBen Stokes-led England.
