I think it's purely between Chahal and Yuvraj. It depends of the kind of friendship and bonding they have with each other. They are great cricketers with true sporting spirit. If both share a common understanding, they will acknowledge that it was just a fun element. Even otherwise, if Yuvraj had sensed that it would have hurt Chahal's sentiments, he would proactively apologize even without we trying to demand on Chahal's behalf. Let's allow them to handle, nobody else can handle it better than they themselves. If we post comments based on our own assumptions and perceptions, it might negatively influence and tamper their friendship/bonding.
