Real Madrid's Trent Alexander-Arnold said former Liverpool team-mate Diogo Jota "was there with me today" after helping the Spanish team reach the semi-finals of the Club World Cup.
Alexander-Arnold and Jota spent five years together at Liverpool before the England full-back signed for Real in June.
Jota, aged 28, died in a car crash on Thursday along with his brother Andre Silva, who was 25. Their joint funeral was held on Saturday in Portugal.
Alexander-Arnold has been featuring for Real Madrid at the Club World Cup in the United States and assisted Fran Garcia's goal in their 3-2 win against Borussia Dortmund in the quarter-final in New Jersey.
