Chelsea defender David Luiz is confident they're back on track.
"If the results don’t come now, they will come in the future," said Luiz. "In the last four games I’ve played really well, at the top level and with confidence. I need to continue this work and mentality.
"Every day work, work, work, this is the key to football because if you don’t, other guys work more than you do and they kill you."
