David Luiz hails the unity of his Brazilian team after their 1-0 win against Serbia and highlights the relationship he has with Thiago Silva.

David Luiz has hailed the unity in the Brazil national team following their win against Serbia and highlighted his special bond with Thiago Silva.

The Brazilian defender is set to join compatriot Silva as a Paris Saint-Germain player on June 10 after Chelsea accepted a £40 million bid from the French club.

Luiz took to Instagram to praise the spirit and unity of the Brazilian side ahead of their World Cup campaign that kicks off next Thursday and stated "all together we are something".

The picture shows the soon-to-be former Chelsea defender helping his soon-to-be PSG teammate and partner in defence Silva to his feet. The 27-year-old highlighted the strength of their partnership after the duo saw Brazil keep their third consecutive clean sheet in a 1-0 win against Serbia.

"Thank God for being part of this family! United always bro," Luiz wrote on his Instagram post.

Brazil have now kept seven clean sheets in their past nine matches and have conceded just six goals in 16 games during the course of the last 12 months.

Luiz Felipe Scolari's side are a solid unit defensively, and Luiz and Silva are arguably the best centre-back pairing on the planet heading into the tournament.

PSG clearly believe that they are the best in the world and have splashed £40m to bring Luiz to Paris, where he will partner his Brazilian 'brother' at the heart of the defence.

Brazil open their World Cup campaign on home soil against Croatia on Thursday and will hope to get off to a winning start.

The Selecao are boosted by the fact that Croatian striker Mario Mandzukic will miss the opening game through suspension. However, the pressure will undoubtedly be on the attacking players such as Neymar to perform.

The 2014 World Cup favourites will rely on their defensive partnership to keep them solid at the back and will look to dominate teams with their high-tempo attacking style of play as a result.
