Tennis legend John McEnroe has identified the rise of towering power-hitters as a primary obstacle preventing Carlos Alcaraz from matching the historic Grand Slam title counts of Novak Djokovic, Rafael Nadal, and Roger Federer. Speaking on Greg Rusedski’s Off Court podcast—as reported by We Love Tennis—the former world number one detailed how players capable of dictating pace on fast surfaces can disrupt the Spanish star’s rhythm and drain his physical stamina.
How Power Hitters Disrupt Alcaraz at Majors
McEnroe pointed directly to competitive encounters against big-serving opponents like Ben Shelton as a blueprint for how the sport’s elite youth can trouble the multiple major champion. During their grueling five-set battle at Flushing Meadows, Shelton used his formidable reach and heavy serve to take the initiative away from Alcaraz, ultimately pushing the defending champion to his physical limits.
À mon avis, l’une des raisons pour lesquelles Carlos aura tant de mal à se rapprocher des chiffres de Novak et Roger en Grand Chelem, c’est qu’il existe des joueurs de grande envergure, comme Shelton, capables de monter sur le court et de disputer des matchs incroyables,
McEnroe explained on the podcast, noting that such adversaries can occasionally make Alcaraz feel desperate on court.

While tracking Alcaraz’s progression through the tournament, observers anticipated another deep run, but McEnroe observed that the Spaniard failed to deploy his absolute best tennis while his body eventually began to fail him under the sustained pressure applied by Shelton.
Athletic Brilliance and the Puzzle of On-Court Joy
Beyond the tactical challenges posed by big servers, coverage from Tennis365 highlights McEnroe’s continued fascination with the 23-year-old’s unique temperament. Having previously described Alcaraz as a natural freak athlete who ranks among the top five movers ever to step onto a tennis court, McEnroe admitted on the Tennis Insider Club podcast that he remains somewhat bewildered by the constant happiness Alcaraz exhibits during high-stakes competition.
I watch Alcaraz. I’m like, ‘how the hell is he so happy on the court all the time?’
McEnroe said, comparing the Spaniard’s visible exuberance to the graceful ease once displayed by Roger Federer. I wish I knew how they were able to handle the pressure that way, the expectations. And to be able to, like… I mean, I love Alcaraz. He’s my favourite guy to watch.
Longevity and the Road Ahead for the Spanish Star
Despite noting the physical toll exacted by aggressive opponents, McEnroe remains highly optimistic about Alcaraz’s long-term trajectory if he manages to maintain his physical well-being. According to assessments shared with Tennis365, the seven-time major champion believes Alcaraz is capable of securing at least ten more Grand Slam titles if he steers clear of career-derailing injuries.
If he stays fit, he could win at least ten more majors,
McEnroe stated, contrasting Alcaraz’s current outlook with contemporaries like Bjorn Borg, whose career concluded abruptly at age 25. McEnroe emphasized that keeping Alcaraz healthy for another decade—reaching age 33—is vital for the sport, praising the player’s vibrant personality and immense value to the tennis ecosystem.
