Reaching the quarterfinals at the Libema Open has been the best result for Mark Lajal in the 2025 season.

He then received a victory via walkover against fifth-seeded Hubert Hurkacz in the second round.

These two players have not played each other previously, but being the higher-ranked player, Bergs is the favorite to win the upcoming match.

Predicted winner- Zizou Bergs

Karen Khachanov vs Gabriel Diallo

Third-seeded Karen Khachanov is set to take on Canada's Gabriel Diallo in the quarterfinals of the 2025 Libema Open.

Khachanov's best result of 2025 was reaching the semifinal of the Barcelona Open, where he lost against the eventual champion Holger Rune. At the Libema Open, he received a bye in the first round, and then won 6-3, 5-7, 7-6 (4) against American qualifier Mackenzie McDonald in the second round.

Gabriel Diallo had his best run of 2025 in Madrid, where he reached the quarterfinals as a lucky loser, falling short against Lorenzo Musetti. At the Libema Open, he started with a 7-5, 7-6 (2) win over Aleksandar Vukic and then upset sixth seed Jordan Thompson in the second round, winning 4-6, 6-1, 7-5.

Khachanov has won all three matches against Diallo, including a 7-6 (4), 4-6, 6-3, 6-3 win in their last meeting at this year's Australian Open. The head-to-head supremacy makes the Russian player the favorite for the upcoming match as well.

Predicted winner- Karen Khachanov

Ugo Humbert vs Nuno Borges

Second-seeded Ugo Humbert will face seventh-seeded Nuno Borges in the quarterfinals of the 2025 Libema Open.

Humbert's best result in 2025 was successfully defending his title in Marseille, with a win over Hamad Medjedovic in the final. At the Libema Open, he got an opening-round bye, and then won 7-5, 6-3 against British qualifier Dan Evans in the second round.

Nuno Borges' best result in 2025 was reaching the semifinal at the ASB Classic, losing against Zizou Bergs in three sets.

Borges won the only match he played against Humbert 3-6, 7-6 (2), 7-6 (4) at the Canadian Open last year. However, being the higher seed, Humbert is the favorite to win the upcoming match.

Before putting out any information in the public domain, Sagnik makes sure that every element of his content is well-researched and backed with credible data so that there is no misinterpretation of facts or quotes and ethical standards are maintained.

He is a fan of former player Roger Federer, and just like his favorite player, Sagnik likes to bring perfection to his write-ups by providing concise and on-point content. Speaking of the ‘GOAT’ debate, Sagnik believes that it is a bit unfair to compare the legends of the game from different eras who have played on different terms. But if he were to pick one, he’d go for Novak Djokovic based on his tally of 24 Grand Slam titles.

When not writing about tennis and technically analyzing the sport, which he believes are his 'forte', Sagnik indulges in reading books.
