Ronaldo's signature goal celebration involves a mid-air spin followed by his landing "si!" (sometimes spelt "siu"), which is "yes!" in Spanish. It's an expression of how much you enjoy scoring. Typically, when Cristiano Ronaldo leaps and lands, the crowd roars the word with him, creating a loud noise that echoes throughout the stadium.

The'si!' celebration, which Ronaldo first performed while at Real Madrid, has come to be associated with him in the latter stages of his career... At the 2014 Ballon d'Or ceremony, he famously yelled "siiiiii!" on stage after winning the trophy before long-time rival Lionel Messi. The outburst caused a mixed reaction, with many people left confused.

Al Nassr is eager to sign Casemiro

Playing time has been difficult for Casemiro ever since Ruben Amorim came over at Old Trafford. During Manchester United's 2-1 Europa League triumph against Rangers, the 32-year-old was benched and missed the team's previous three league games. Although the club has given its approval, the management does not intend for Casemiro to leave. According to sources, Ronaldo has instructed Al-Nassr's top management to buy Casemiro this January in an attempt to keep Stefano Pioli's team from collapsing further in their pursuit of the Saudi Pro League title.
