WATCH: Carlos Alcaraz & Andrey Rublev's Madrid Open QF garners attendance from star soccer players Luka Modric, David Villa, Raul & others

The Madrid Open between Carlos Alcaraz and Andrey Rublev was attended a few well-known soccer players.

Alcaraz came into the Madrid Open looking to kick start his European clay-court season, which he wasn't able to start due to a right arm injury. He was also looking to successfully defend his title for a thrid consecutive time. The Spaniard defeated Alexander Shevchenko, Thiago Seyboth Wild, and Jan-Lennard Struff en route to the quarterfinals.

Rublev, on the other hand, who was looking to find his rhythm back after four consecutive losses, has been very successful so far and defeated Facundo Bagnis, Alejandro Davidovich Fokina, and Tallon Griekspoor to reach the final eight.

The duo butted heads for almost two hours during their quarterfinal match, with the Russian coming out on top 4-6, 6-3, 6-2, thus ending Alcaraz's hope of a three-peat in Madrid.

Football royalty Luka Modric, Raul and David Villa were all in attendance at the Manolo Santana Stadium, as were the likes of Koke and Sergio Reguilon.
