Luis Suarez, Koke, Joao Felix and Jan Oblak have all contributed to Atletico Madrid's great start to the 2020/21 season, but there are some other players who have unexpectedly made a huge impact on the team.
Los Rojiblancos have won 13 of the 16 games they've have played so far to be crowned LaLiga Santander winter champions.
Let's take a look at five players who have taken a step forward for Atletico this season.
The Montenegrin centre-back has been Atletico's best defender this season despite competing for a spot with talented players such as Jose Maria Gimenez and Felipe.
While the former has struggled with injuries, Felipe has yet to rediscover his form in this first round of the season.
Meanwhile, Savic has stepped up to lead the team both in the dressing room and on the pitch when needed.
After an unconvincing first season for Atletico, Hermoso came close to departing the club in last summer's transfer window.
In the end, he stayed at the team and has managed to establish himself in Diego Simeone's three-man defence.
Hermoso has contributed in attack too, having scored a couple of crucial goals against RB Salzburg and Real Sociedad.
After a two-year exile in China, Carrasco struggled in his return to Atletico Madrid last season but managed to bounce back in 2020/21.
Playing as a left-wing-back in Simeone's 3-5-2 formation, the Belgium international has stood out with his performances, having scored decisive goals such as Atleti's decider against Barcelona.
He arrived at Los Rojiblancos to fill in the void left after Rodrigo Hernandez's departure to Manchester City, but has become something more than a holding midfielder.
Llorente has already played in the majority of midfield and attack positions so far this season and has shined regardless the task he was assigned to carry out.
With as many as seven goals and four assists in all competitions so far, the former Real Madrid midfielder has been one of LaLiga Santander's most outstanding players.
The Frenchman is undoubtedly the most unexpected breakthrough player for Atletico.
After two campaigns where he hardly contributed anything in attack, Simeone has converted him into a solid midfielder.
His recent performances are reminding fans of the player who shined at Monaco and became a world champion with France in 2018.
