The two sides produced an extended five-goal spectacle in Saudi Arabia that was eventually settled by a Federico Valverde winner, scored in the eighth minute of extra time. But it was a couple of goal celebrations that caught the eye most.
Carlo Ancelotti's side scored first in Riyadh, with in-form Vinicius Junior sprinting clear of the Barca back line to thrash a powerful finish past Marc-Andre ter Stegen to open the scoring with his 15th goal of the season.
The Brazilian then marked his strike with a cheeky piece of choreography.
Luuk de Jong levelled things for Barca shortly thereafter with his third goal in three games, before a Karim Benzema tap-in midway through the second half shunted Real back into the lead with 72 minutes played.

Then, things started to get really interesting.
Having only just returned from injury, the young winger rushed away to celebrate and amid the excitement began to hit the Cristiano Ronaldo trademark "SIUUUU!" celebration before seeming to remember which side he was on (and the fact that he was wearing Lionel Messi's No. 10 shirt) halfway through his leap and pulling out.

With the regulation 90 minutes played and the scoreline level at 2-2, extra time was ushered in. It didn't take Real long to break the deadlock once again as midfielder Valverde latched onto a Rodrygo cross to pass the ball into the back of Ter Stegen's net.
Then, much like Ansu's botched celebration, the Uruguay international attempted to goad Barca fans by mimicking Messi's famous "shirt aloft" Clasico celeb from 2017.
Alas, some unfortunate billowing of Valverde's shirt saw it fail to fully unfurl, which rather gave him the look of a man trying to get dressed in the dark.

Thankfully, the Madrid fans who had travelled to Saudi Arabia were on hand to pick up the slack, greeting Valverde's winning goal with a giant "SIUUUU!" of their very own from the stands.

The impact of Ronaldo and Messi on Real Madrid and Barcelona is clearly still going strong. And long may it continue.
