Although underwhelming at times, Los Blancos took advantage of an awful season from Barcelona to win La Liga in 2019/20 last season.
Despite featuring in defence, Ramos was often the difference maker, whether that be through a towering defensive performance or a match-winning goal.
His importance to the team has continued into 2020/21 when he is once again their talisman.
Casemiro, who has won two titles and four Champions League alongside the legendary Spaniard, has praised his team-mate's leadership qualities.
“Sergio is a leader in the dressing room and on the field," he said ahead of Real Madrid's Champions League game against Inter on Wednesday.
"It’s a pleasure to have shared all these years with him. What he’s doing now is writing his name in the club’s history books.

“He’s a player who never gives up. He always wants to fight and he always wants to win. He pushes the team forward, and he’s a leader and a role model for us.”
Madrid will have to contend with Ramos for the trip to the San Siro, in what has arguably became a must-win game for Los Blancos if they retain any aspirations of topping the group.
After starting their campaign with a surprising loss versus Shakhtar, they drew with Gladbach before very narrowly defeating Inter before the international break.
They are currently third in Group B.
