World No.1 tennis player Novak Djokovic’s visa being cancelled on his arrival in Melbourne to play in the season-opening Grand Slam, has the potential of turning into a diplomatic crisis between Australia and Serbia.

Australian Prime Minister Scott Morrison had re-iterated on Thursday that nobody was above the country’s border rules as he ordered cancellation of Djokovic’s visa.
On Friday, as the defending Australian Open champion’s lawyers tried to get the decision reversed, Serbian president Aleksander Vucic spoke to the media, hitting out at the supposed politics behind Djokovic’s detainment.
