Novak Djokovic battled back from 0-2 down against Jannik Sinner to reach the
Wimbledon semifinal once more but his water bottle stole the show.
His comeback left many viewers scratching their heads, as did a mysterious drink that he was passed by his team mid-way through, which some claimed sparked his return to form. Eagle-eyed fans spotted the 35-year-old being handed a white bottle, before gesturing to his team several times. He then began to seemingly both inhale and drink its contents all at once.
The whole exchange really confused a lot of tennis fans watching back at home.
Writing on Twitter, one viewer said: "What’s in the white bottle? it didn’t look like a drink."
Another chipped in: "What is in the bottle? I swear he inhales it."
