Harbhajan Singh gave Arjun Tendulkar a tag of 'Good boy’ after the cricketer-turned-commentator spotted him selling radios outside Lord's. Earlier, he was all over social media for helping out the groundsmen on a rain-affected day in the second Test between India and England at Lord's.

Sharing the picture of Arjun, with a broad smile, he wrote, “Look who selling radios @HomeOfCricket today.. sold 50. Rush guys only a few left. Junior @sachin_rt #Goodboy”

The junior Tendulkar is training with MCC Young Cricketers in London. He was recently in news for getting his maiden call for India's U-19 team.

On Friday, during the rain-affected day two of the second Test, Arjun came out to help the ground staff at Lord's. His help was appreciated by the management of the cricket ground.

“Not only has he been training with @MCCYC4L recently & but he has also been lending a helping hand to our Groundstaff!#ENGvIND#LoveLords,” the official Twitter account of Lord's wrote.

Arjun, who is a left-arm fast bowler, had also helped the Indian batsmen in nets. He even bowled to Indian skipper Virat Kohli.
