The Brazilian anchorman has missed the last few games with injury.
But with the Reds having won every game since that fixture, Lucas is likely to struggle to infiltrate the side's midfield.
Even Liverpool icon Steven Gerrard is set to struggle to nail down a regular role under Brendan Rodgers for his last few months at the club, with Jordan Henderson in superb form in 2015.
Lucas, who posted on Instagram via Sky Sports that he was back in full training, has made just 15 league appearances this season for Liverpool, following on from supporting roles in the last couple of Premier League campaigns.
However, the Brazilian is still young enough at 28 to make an impact for the Reds, especially considering Liverpool skipper Gerrard is set to depart for LA Galaxy in the summer.
His Liverpool future will likely depend on whether Rodgers chooses to recruit a big name midfielder to soften the departure of Gerrard, or go with those he currently has at the club.
Having suffered a serious knee injury in 2011, the former Gremio man has done well to battle back to fitness, even if he hasn't quite matched the form he displayed before that injury.
But considering he's now in his eighth season at Anfield, and considering there is no other midfield enforcer quite like him on Liverpool's books, there is plenty of reason to think Lucas may get further chances in the future, even if he doesn't see much football in the next few weeks.
