Lionel Roux, tennis consultant on Humbert-Alcaraz: "Ugo can beat anyone when he's good".

The clash of the number 1 players, between Carlos Alcaraz and Ugo Humbert, will be a decisive moment in this Friday's Davis Cup match between Spain and France.

As a reminder, Les Bleus, beaten 2-1 by the valiant Australians, now have no choice. They'll have to overturn the Spaniards to keep their hopes of qualification alive.

When asked about the upcoming match, Lionel Roux, tennis consultant for BeinSports, focused in particular on the second match of the confrontation, the duel that will pit the French No. 1 against the man who has won two Grand Slam titles this season, but seems to have struggled to regain his form in recent weeks: Alcaraz.

For Roux, victory is far from assured for the world No. 3: "In the Davis Cup, we feel that Ugo has a mission, because of his role as No. 1.

Even on the bench, he encourages his team-mates a lot.

As for Alcaraz, I found him hesitant on Wednesday (during the Spain/Czech Republic match), making a lot of forehand and return errors.

Faced with someone like Ugo, who's going to attack him even more, who's going to give him less time, it can be complicated.

Obviously, he can settle, but Ugo, with his aggressive left-handed style, can beat anyone when he's good."
