Alexander Zverev is one player who will be truly glad to see the back of 2025.

The world number three has endured a torrid time of things pretty much since he made the final of the Australian Open before losing comprehensively to Jannik Sinner.

Zverev provided an update on his back injury after this weekend’s Laver Cup, which threw up another string of questions about the German’s current form following some torrid displays.

Carlos Alcaraz tried to fire Zverev up in the deciding rubber against Taylor Fritz, but ultimately, he came up short once again as Team World claimed a big victory.

It’s a worrying time for Zverev and right now, there appears to be little light emerging from the end of a very dark tunnel.

The surface in San Francisco hardly helped Zverev when it came to his serve, with that side of his game usually his get-out-of-jail card.

However, the signs of Zverev improving his form at the moment are non-existent, and it would appear the player is going through a real struggle right now.

Zverev had the worst record of any player at the Laver Cup, playing twice and losing twice, both in singles matches to Alex de Minaur and Taylor Fritz.

He was responsible for five dropped points for Team Europe, and playing in big matches appears to be a real mental challenge for Zverev at the moment.

Although Zverev got to the final in Melbourne back in January and reached the quarterfinal at the French Open, he was sent packing in rounds one and three at Wimbledon and the US Open, respectively.

For a player with so much quality that simply won’t do…

Zverev’s serve is way off the pace

Last year, Zverev was the leading server on the ATP Tour with a serve rating on the tour’s official website of 299.9.

This year, the German is below Giovanni Mpetshi Perricard, Sinner and Fritz in fourth place with a rating of 295.2.

Furthermore, the pace of Zverev’s serve is really crippling him right now, with his serve at the Laver Cup down a staggering 14 MPH based on the rest of the year.

Zverev’s serve is down 14 MPH from his season average so far.

If he’s compromised, why is he playing? It’s a team event. I don’t get it.

That might imply that Zverev was compromised during the event, but if that was the case, why did he choose to go ahead and play in a tournament that both teams are always so keen to win?

It’s not clear what the rest of the year holds for Zverev, but he’s got to shake himself out of his current rut if he’s to eventually win one of the game’s top prizes.
