How quaint it now feels to recall the Novak Djokovic of 12 months ago, by comparison with the up-to-date version. It is inconceivable to relate the bewildered player of last year with the frighteningly invulnerable world No.1 who has swatted aside all-comers at Roland-Garros 2019.
Having haemorrhaged a mere eight games in each of his three rounds to date, Djokovic was theoretically facing a challenging hurdle in the last 16 in the form of Jan-Lennard Struff, who strode on to Court Philippe-Chatrier bearing an impressive list of clay scalps this season. Ninety-three humbling minutes later he exited as Djokovic’s cheapest victory here to date.
