Medvedev comes through against Arnaldi

Daniil Medvedev didn't have a quiet match on Sunday.

Facing Matteo Arnaldi, the Russian needed almost 3 hours of struggle to get through (5-7, 6-4, 6-4).

Maltreated by an uninhibited Italian who was aggressive without overdoing it (39 winners, 22 unforced errors), Medvedev was seriously tested and had to play his best tennis to get through (10 aces, 33 winners, 18 unforced errors).

For a place in the quarter-finals, the world number 5 will face the winner of the duel between Tsitsipas and Muller.
