Carlos Alcaraz was given a scare in the first round of Wimbledon as he was taken to five sets by Fabio Fognini, prompting John McEnroe to issue a warning to the Spaniard

Second-seeded Alcaraz is currently on a career-best 19-match winning streak, but struggled against Fognini who has never been past the third round at Wimbledon.

Alcaraz hopes to become the first player on the men's tour since Bjorn Borg to complete the French Open-Wimbledon double in consecutive years. Alcaraz is only the third defending Wimbledon champion all-time to be taken to five sets in the first round of the following year's Grand Slam.
