Here's a short story:

(CNN) -- They share the same surname -- Djokovic -- but for now at least, that is where the similarity ends. 

Novak is at the pinnacle of his sport and was the center of attention in Dubai after completing in his first victory since winning the Australian Open in January. 

At 20, Marko is four years younger, and 868 places further down the rankings -- and on Monday he slumped to an opening-round defeat in front of his elder sibling. 

Djokovic senior was on hand to watch his brother's elimination, at the hands of Russian qualifier Andrey Golubev, but says that Marko can make his mark in the upper echelons of the game.

"He has to face the pressure of having the Djokovic surname," Novak said in quotes carried by AFP. 

"He's trying to fight with his mind more than with his game. When he is able to focus on that and not on his doubts he can become a world-class player." 

He admitted it was tough to watch Marko's 6-3 6-2 reverse. "It was difficult for me to sit courtside," he said. "I have not done it too much. 

"At least when I'm playing I know what's going on. But I was happy my brother got a wild card. He is not at his level yet, but he's getting there." 

As for Marko, he said there were plenty of positives and negatives to being the brother of the world's No. 1 player.  (End of story)
