Barcelona are working to improve their squad for next season, particularly in defence.

Defenders like Jules Kounde, Kalidou Koulibaly and Andreas Christensen could come in to strengthen the team at the rearguard.

Let's look at some interesting centre-back partnerships Barca fans could see at their favourite team next term.

Araujo-Pique
Gerard Pique and Ronald Araujo played a few times together last season. The pairing worked for Barca, with the combination of Araujo's strength and Pique's experience proving competent.

However, Pique is ageing quickly and has become injury-prone. The good thing is, promised Cules to be at his best next season. Let's wait and see,

Kounde-Araujo
Barcelona have been strongly linked with Jules Kounde. The transfer is looking likely by the day.

A partnership between Kounde and Araujo would be quite interesting next season. What we would see is sharpness and robustness from two young and powerful defenders next season.

Christensen-Araujo
Christensen is noted for his superb technique and impressive passing.

Reports say Barca have already signed him as a free agent. A partnership between the Dane and Araujo will not a bad idea. It could be a perfect reflection of Xavi's style.

Koulibaly-Araujo
Perhaps this would be the most powerful partnership to see next season - if Barcelona succeeds to sign Koulibaly next season.

Who wouldn't want to see Koulibaly's experience and power, partnering with Araujo's robustness and agility?

The Blaugrana could make it happen if they open their checkbooks for the Senegalese powerhouse.

Christensen-Garcia
An unlikely partnership we could see is Eric Garcia pairing with Christensen. Both players possess great technique and are good in the air.

However, they've individually been accused of being error-prone.

Which partnership would you prefer to see next season?
