Novak Djokovic is battling a tough challenge at Wimbledon. The 38-year-old, a seven-time champion at SW19, entered this Grand Slam aiming for his 25th major title. He’s faced strong opponents, dropping only one set to Alexandre Müller in the opening round. Now, he’s through to the Round of 16. But Alex de Minaur is proving to be a serious threat, and John McEnroe isn’t holding back with his honest takes.

On Monday, the Centre Court clash started shakily for the Serbian. He lost the first set 6-1 to the Australian No.1. Djokovic served four double faults, hit less than half of his first serves, won just 18 percent of points on his second serve, and racked up 16 unforced errors in the first 30 minutes. This shaky start stunned both Centre Court and McEnroe.

Speaking to the BBC, the ATP legend made a bold prediction after watching Djokovic’s rough start. “It’s not going to happen that he continues to play this badly,” he said. “If he did for two more sets, he’d quit on the spot. I would predict, if he plays like this for another two sets – I don’t think there’s a prayer it’s going to happen – but this is incredible to see him play like this.” Yikes!

Despite the rough start, Djokovic fought back. He broke back in the second set and, after saving several break points in the decisive game, took it 6-4. Still, De Minaur looks physically stronger, while Novak struggles with his knee.

McEnroe remains conflicted watching Nole. He added, “I can’t remember him playing a worse set than this – it’s been years, literally. He is absolutely disgusted with himself. [De Minaur] didn’t have to do anything that he didn’t want to do out there.”

Now in the third set, can Novak Djokovic rally to win and reach his 16th Wimbledon quarterfinal? Only time will tell! Stay tuned for every point and play from the Championships via our Live Blog.

Update: Novak defied the odds and took the win! Following that second set victory, the Serbian maestro kept up the pace to take another two sets, winning by 1-6, 6-4, 6-4, 6-4! Talk about a comeback. He’s certainly relieved.

If Djokovic wins this tournament, he will secure his 25th major title. He will also tie Roger Federer’s record for the most Wimbledon trophies won. While John McEnroe was convinced Djokovic wouldn’t get past his match, the ATP legend backed him up not too long ago.

John McEnroe fends off critics of Novak Djokovic

The Serbian has often found himself at odds with the Wimbledon crowd, which prompted John McEnroe to jump to his defense. McEnroe insists Djokovic deserves more respect for his incredible achievements. He told The Metro, “Novak has not only equalled them [Federer and Rafael Nadal] but surpassed them in overall achievements, which seemed impossible.” He added, “Both of those guys, Rafa and Roger, they are total class acts.”

Djokovic, a seven-time Wimbledon champ, is aiming for an eighth title this year—tying him with Roger Federer’s iconic record. Despite his success, Djokovic hasn’t enjoyed the same warm welcome on Centre Court that Federer did, who was always a fan favorite.

McEnroe called out the unfairness head-on. “They are loved and respected around the world. Novak gets the unfair treatment. He’s the villain, the bad guy. I think it’s been unfair, honestly, because he is great for the game. On and off the court.”

Now, with Djokovic set to face Flavio Cobolli in the next round, all eyes are glued to him. Will Nole make it to the semis again? Tell us your thoughts in the comments below!
