Trent Alexander-Arnold fires message as ex-Liverpool star plays key role in Real Madrid's first win at Club World Cup

Alexander-Arnold had a rather dull Real Madrid debut against Al-Hilal last week on the back of his controversial transfer from Liverpool. However, he has proven his quality in Los Blancos' first Club World Cup win against Mexican side Pachuca.

Alexander-Arnold did not manage to get a clean sheet or a goal contribution; however, the Englishman showed off his defensive prowess for a Real Madrid side that went down to 10 men after Raul Asensio's seventh-minute red card. The 26-year-old has now shared his first words after Los Blancos' win.

On Instagram, Alexander-Arnold posted photos from the win, and wrote: "First win in white! Hala Madrid."

Real Madrid will face off against RB Salzburg next in the Club World Cup, and Alexander-Arnold will be a starter as Los Blancos know that a loss could see them knocked out of the tournament.
