Djokovic is more single-minded than Murray in his approach to winning tennis matches.
He will look to overpower Murray with scorching backhand strokes and precision shots down the line. He controls a rally with topspin, but he also loves to hit a flatter, harder pace with his winners. Above all, he loves to lace his backhand down the line. He is strong off both wings with the ultimate 21st century brand of baseline power.
Though Djokovic has worked more on his game to improve at the net, he is still reluctant. He will come in to net to finish shots a little more often against the defensive-stalwart Murray who can track down some of the toughest shots in tennis.
Djokovic must also serve well. When his first serve is on and his second serve consistent, he is difficult to beat. It's often the indicator of his performance, though not his strength.
He would like to get Murray in a street brawl of baseline exchanges. Nothing fancy, but pure topspin groundstrokes. The more this occurs, the better Djokovic's chances for victory.
