Barcelona Transfer Rumours: Spanish Giants Must Maintain Pursuit of David Luiz

Barcelona made the signing of the summer back in June when they landed Brazilian superstar Neymar. However, the Catalan giants would be fooling themselves if they believe they are strong enough defensively to win multiple titles this season.

The Spanish champions surrendered 40 goals in league play last year and looked dismal at the back in Copa del Rey and Champions League defeats to Real Madrid and Bayern Munich respectively.

That's why Barca is best suited to continue their pursuit of dynamic Chelsea defender David Luiz.

According to The Guardian's Tom Bryant, Barcelona hasn't let Chelsea's rejections discourage them from chasing improvement:

"

Barcelona are looking at the cash in their piggy bank and are looking to offload 35 million shiny pound coins on Chelsea. They'll expect David Luiz in return, mind.

"

Luiz is a key piece to Chelsea's puzzle this season. Jose Mourinho knows the Blues have a shot to win the Premier League and make another deep run in Europe if he's on board. Consequently, the Portuguese manger likely wants him to stick around.

But money talks, and if Barcelona bring enough to the table, Chelsea will have no choice but to listen.

It goes without saying that Luiz would be a massive addition for Barca. The 26-year-old defender had an average match rating of 7.16 last season in the Premier League, according to WhoScored.com, scoring two goals, assisting on two others and finishing the season with a pass success rate of 81.1 percent.

Luiz's passing strength points to his versatility. Whether he's making stops at the back or firing up the attack and taking on a midfield role, Luiz rarely goes unnoticed on the pitch.

Captain Carles Puyol isn't getting any younger and can no longer be expected to play at a high level year after year.

Barcelona's prolific attack (115 goals in 38 matches) was enough overcome their lackluster defense and lead them to another league title last season. However, their shaky unit was exposed in troubling losses to elite clubs like Madrid and Bayern. 

Luiz could help stabilize that unit and make Barcelona a more complete squad from top to bottom.

For this reason, Gerardo Martino and company must remain in hot pursuit of David Luiz this summer, regardless of what obstacles Chelsea throw at them along the way.
