Zizou Bergs vs. Gabriel Diallo Preview

Bergs has battled through a tough draw to reach the final. The Belgian moved past compatriot Alexander Blockx in a tight three-setter to begin his campaign. This was followed by another hard-fought three-set win over fourth seed Alexei Popyrin. He later registered his first straight-sets win of the tournament when he defeated Estonian qualifier Mark Lajal in the quarterfinals.


Bergs produced his most dominant performance in the semifinals by swiftly securing a win over Reilly Opelka 6-1, 6-4. His return game turned out to be a highlight as he broke the big-serving American three times without facing a single break point himself.

Gabriel Diallo, on the other hand, had a breakthrough week in ‘s-Hertogenbosch. The 23-year-old Canadian secured exceptional wins to reach the final. He defeated third seed Karen Khachanov in the quarterfinals before upsetting second seed Ugo Humbert 6-3, 7-6(4) in the semifinals.

Diallo’s serve helped him throughout the tournament, and his aggressive, flat-hitting baseline game also aided him on the grass. Diallo became the first Canadian male to reach the final at the Libéma Open.

Zizou Bergs vs. Gabriel Diallo Head-to-Head

Bergs and Diallo have only played each other once at the ATP main-draw level. The Canadian secured a smooth 6-1,6-2 win over the Belgian in the first round of the 2025 Mutua Madrid Open.

Zizou Bergs vs. Gabriel Diallo Prediction

Diallo’s powerful game is naturally suited for grass. The Canadian has hit 40 aces in this tournament and has won over 70% of first-serve points against both Khachanov and Humbert. His flat, aggressive groundstrokes give him an edge in baseline exchanges.

Bergs’s four matches in s-Hertogenbosch have featured a total of five sets that have gone to tiebreaks. His movement and intensity have helped him advance through tough opponents. However, the Belgian’s serve has been inconsistent throughout the tournament. While he has managed 25 aces, he has also committed 27 double faults. Such lapses could prove costly against someone like Diallo.

If Diallo maintains his serving rhythm and stays aggressive on the return, he will likely put Bergs under constant pressure. The Canadian’s ability to dominate short points and take advantage of weak second serves could set the match in his favor.

Prediction: Diallo to win in straight sets.
