Defensive Midfielder: Casemiro (Real Madrid)
Atletico Madrid manager Diego Simeone has said that when it comes to team balance, Casemiro is the most important player for Real Madrid.
The Brazilian is vital in breaking down opposition play, with his aggression and crunch tackling. He can also pop up with goals at crucial moments.
Right Midfielder: Luka Modric (Real Madrid)
It's difficult to believe that Luka Modric is 36, as he plays with a youthful exuberance that can put younger players to shame. His work rate is exemplary, and he remains a vital cog for his team.
He sets the tempo of games by controlling possession and making excellent distributions. Modric also often creates space for his teammates to thrive.
Central Midfielder: Toni Kroos (Real Madrid)
Toni Kroos, the third piece of Real Madrid's legendary midfield, is the archetypical modern attacking midfielder. He is dynamic and hard-working, and offers invention.
The German's biggest trait arguably remains his exquisite set-piece deliveries. He's averaging a staggering 95.1% passing accuracy, and has contributed three goals this season.
Central Midfielder: Yannick Carrasco (Atletico Madrid)
He didn't immediately hit the ground running after returning from China in January last year. However, Yannick Carrasco eventually settled in, and played a big part in Atletico Madrid's La Liga triumph last season.
With two goals and four assists this campaign, it's safe to say the Belgian has maintained that form. It'll be interesting to see how Real Madrid deals with Carrasco's threat.
Left Midfielder: Vinicius Junior (Real Madrid)
The breakout star of the year, Vinicius Junior has finally produced the form that was always expected of him since he arrived in Madrid three years ago.
He has struck ten times in the league this season, second only to Karim Benzema. Vinicius has also assisted three more goals, breathing fire at the moment.
