Left-Back - Sergio Reguilon (Sevilla)
Sergio Reguilon narrowly beats out fierce competition from Real Madrid's Ferland Mendy to take his place in this season's best La Liga eleven. The Sevilla full-back has been nearly flawless under Julen Lopetegui and has put in several notable performances.
The Spaniard has featured in 29 La Liga games for Sevilla this season and has scored 2 goals. Reguilon is known for his ability to make an impact in both halves of the pitch and his forays in the final third have resulted in four assists.
Sevilla has a better defensive record than Barcelona this season and Reguilon certainly deserves his fair share of credit for making the Andalusians a potent La Liga force.
Centre-back - Sergio Ramos (Real Madrid)
It has often been a case of 'cometh the hour, cometh the man' for Real Madrid in La Liga this season. In his own half, Sergio Ramos is a leader and a monster packed into a single imposing frame. In the opposition's half this season, the Real Madrid captain has become a force to reckon with.
The fact that Sergio Ramos has scored more La Liga goals this season than Barcelona forward Antoine Griezmann certainly puts the defender's goalscoring exploits into perspective. Ramos has scored 11 goals in La Liga this season and is the most prolific defender in the history of the competition.
Ramos has become his side's designated penalty-taker and will go down as one of the best Real Madrid captains in history. The Spanish defender is arguably the best defender in La Liga at the moment and has seen his stock soar this season.
Centre-back - Raphael Varane (Real Madrid)
With Sergio Ramos unsurprisingly stealing the limelight in Real Madrid's defence, Raphael Varane's incredible performances in La Liga have often slipped under the radar this season. The numbers, however, speak for themselves.
With the French defender in its ranks, Real Madrid has conceded only 25 goals this season and Varane has been one of the side's most consistent performers. The centre-back has pace and tenacity in equal measure and can keep up with some of the fastest forwards in La Liga.
Raphael Varane is only 27 years of age and is entering the peak of his career. The defender was always supremely talented but has flourished into a truly world-class player this season under Zinedine Zidane and will serve Real Madrid well in La Liga for years to come.
Right-back - Jesus Navas (Sevilla)
Jesus Navas has transitioned into a right-back in the recent past and made the role his own this season with a string of exceptional performances for Sevilla in La Liga.
Under Julen Lopetegui, the Sevilla captain has undergone a renaissance and has shown a vast improvement in the defensive aspects of the game. In the final third, Jesus Navas is still a lethal force and has created several crucial goals for Sevilla this season.
The former Manchester City winger has 7 assists in La Liga this season and his exploits have seen Sevilla qualify for the Champions League. The Spaniard is an inspirational figure in the dressing room and has become a lynchpin in Lopetegui's side.
