Novak Djokovic was visited twice by a doctor for a stomach issue and given what he called “miracle pills” during a 6-1, 6-7 (7), 6-2, 6-2 victory over Alexandre Muller in Wimbledon’s first round on Tuesday night.

Novak Djokovic thanked "doctors' miracle pills" after he overcame feelings of discomfort and the loss of a set to launch his mission to win a record 25th Grand Slam at Wimbledon. The veteran Serb, a seven-time winner at the All England Club, beat French world number 41 Alexandre Muller 6-1, 6-7 (7/9), 6-2, 6-2 in a late-night match on Centre Court.

Novak Djokovic admitted to feeling his ‘absolute worst’ on court until the doctor’s ‘miracle pills’ restored eased a stomach issue and helped him fight past Alexandre Muller in four sets. The first round clash was delicately poised at one set each when Djokovic asked for the doctor following the third game of the third set.
