MONTE CARLO, April 12 — Novak Djokovic avenged last year’s Monte Carlo Masters defeat by Lorenzo Musetti to reach the quarter-finals yesterday along with Jannik Sinner, while Daniil Medvedev launched into a furious tirade during his defeat.

World number one Djokovic made a poor start and endured a second-set wobble before coming through 7-5, 6-3 against the 24th-ranked Musetti, the man who beat him at the same stage 12 months ago.
