The Brazilian, along with fellow Red Coutinho, will be eager to break into the national side ahead of the biggest competition on the international stage, especially with the added incentive of the tournament being contested in their home country.
Both players performed impeccably towards the end of the 2012-13 season and now the midfielder is hoping that he and Coutinho sufficiently impress to earn the opportunity to represent the five-time world champions next summer.
Recognising the task ahead, Lucas told Liverpoolfc.com: "It's a big season for us. We always talk about this.
"We know how difficult it is to be involved with the squad. I was involved before the injuries so I probably feel worse than him, because I was there and very close to making the Confederations and the World Cup.
"Now it's harder, but this season is a last chance to try and impress and get a place in the national squad.
"The World Cup in our country will be amazing. Every international break that you are not involved in becomes harder, but you have to believe until the end."
