Jose Mourinho’s side travel to Swansea this weekend looking to build on a successful week, but fully aware they can ill-afford any more slip-ups on the road after defeats to Aston Villa and Crystal Palace in their past two domestic away games.
And with Manchester City and Liverpool facing each other at Anfield on Sunday, Luiz is fully confident the two-point gap that separates them and Brendan Rodgers’ league leaders can be clawed back.
"It's still possible to win the league, so come on, let's enjoy the position we are in and believe, like we did against Paris St Germain. We need to have faith because we can still do it," Luiz told reporters.
"Swansea are tough opponents and we've seen in the last few seasons, every time we go there it's a difficult game."
The 26-year-old, who has been more regularly deployed this season as a defensive midfielder as a result of John Terry and Gary Cahill’s strong centre-back partnership, is already relishing the first leg of the Champions League semi-final against Atletico Madrid in Spain.
"It's always good to play the second leg at home, but only if you do well in the first leg," he added.
"If not, your heart can stop, especially if it's like the matches in Paris and Napoli [in 2012], we don't want that to happen again."
