Alexander Zverev recently announced the release of his documentary 'Zverev: Der Unvollendete' -- translated as 'Zverev: The Unfinished One.' The documentary follows his journey after his injury in the semifinals of the 2022 French Open and his eventual comeback.The German shared a half-minute clip on social media as a preview of the documentary, which began with some of his childhood memories of picking up the racquet. It also featured Novak Djokovic speaking about the German, and closed with Zverev feeling devastated after his Roland Garros injury that put him out of action for almost a year."Two things are missing for me: No.1 in the world and a Grand Slam and I could have done it all in that one week. The first though was 'Is my career over now?'" he said at the end of the video post.Tennis fans took to Twitter to react to the World No. 14's post, with many exasperated at his assumption. At the time of the injury, he was one set down against 22-time Grand Slam champion Rafael Nadal, with the second set heading into a tiebreaker.Tennis blogger and journalist Scott Barclay opined that regardless of Zverev's physical status, the 14-times French Open champion would have won the match anyway. He wrote:"My controversial opinion is that even if Zverev hadn't injured himself in that match, Nadal still would have won it."Scott Barclay@BarclayCard18My controversial opinion is that even if Zverev hadn't injured himself in that match, Nadal still would have won it. 🤷‍♂️46517My controversial opinion is that even if Zverev hadn't injured himself in that match, Nadal still would have won it. 🤷‍♂️ https://t.co/UvsoZwwK2CAnother fan joined him in agreement, adding that Zverev's record against top 10 players in Grand Slams was concrete proof that the match was Nadal's to lose."It shouldn't be controversial at all? zverev peaked in set one and still choked it away and ppl think Mr 1-12 v top 10 at grand slams would beat nadal on chatrier?????????" a fan posted.marxist-keninist@tennisywilliams@BarclayCard18 it shouldn't be controversial at all? zverev peaked in set one and still choked it away and ppl think Mr 1-12 v top 10 at grand slams would beat nadal on chatrier?????????661@BarclayCard18 it shouldn't be controversial at all? zverev peaked in set one and still choked it away and ppl think Mr 1-12 v top 10 at grand slams would beat nadal on chatrier?????????Here are a few more reactions:S.S@write2swagatam@BarclayCard18 Not controversial, Nadal have lost only 1 match out of 100s after winning the 1st set at RG, and that's 2021 SF against Novak.

It’s Roland Garros! His home. He did the impossible at AO lol in much worse conditions. It would have probably ended up being a gutting 5 set loss for AZ anyway.9@BarclayCard18 Even though Zverev definitely had the edge at that point in the match, Rafa still would have found a way.
