If anything, David Luiz's Chelsea career has been up and down.

And it's this inconsistency that has kept him out of Jose Mourinho's team this season. 

In the few games the big Brazilian has played, complacency has been the word on everyone's lips, as his frustrating displays so far have taken the spotlight off something but his hair.

Maybe it's the resemblance to Bob Marley that has fueled David Luiz's compilation of calm pass backs, lazy tackles, and moments where you could argue he was too cool under pressure.

Either way, the 26-year-old has been under fire so far this year, and his unusual defensive instincts once again have prompted calls for his move forward to midfield, or subsequently out the Chelsea door.  

The English partnership of Gary Cahill and revitalised John Terry has pushed Luiz further back down the pecking order at the centre of defence, and even right-back Branislav Ivanovic has been preferred this season.

It's clear that Jose Mourinho is finding it hard to trust Luiz, who cost £25 million back in January 2011, even after being an influential member of the current Chelsea squad, where he's brought the Champions League and Europa League to Stamford Bridge.

Although a centre-back, in 2012 he began to be deployed further up the field by Rafa Benitez, in the iconic position in front of the defence, made famous by Chelsea legend, Claude Makelele, in Mourinho's first era.

It was in this position that evoked debates to whether in fact it is his best, after some memorable performances for Chelsea, and the argument is still going on today, so much so that this always seems to be the topic of conversation when David Luiz is mentioned.

Since Claude Makelele left for PSG in 2008, the role, played effortlessly by the Frenchman, hasn't been grasped by any Chelsea player since. The likes of John Obi Mikel and Michael Essien haven't excelled in the role this season, and the less attack-minded Frank Lampard, we know now, still doesn't seem to have that essential defensive instinct we saw from Makelele.

Saying this, the former Vitoria player, a club he started out at defensive midfield, has decreasingly been seen in that role, since Rafa Benitez left, or even on the pitch for that matter. And with a heavy fixture list this Christmas, along with some shaky recent Chelsea performances, especially in defence, David Luiz could be the man to save the title contenders.

Being Brazilian, the Confederations Cup winner has been gifted with great technique and flair, especially as a defender, and combining this with his defensive qualities could really protect the back line significantly.

David Luiz has proven to be an ideal defensive midfielder for Chelsea, and could even become more effective than Makelele, in the way he scores and assists from that position. Even with some sloppy errors, in this position Luiz will be covered by his centre-backs, meaning any mistakes could easily be dealt with.

It's hard to imagine why Jose Mourinho has been as reluctant as he has been.

Considering this is the same person who put faith into the Makelele, the 'French flop' from Real Madrid, surely he can see that David Luiz deserves a chance too. 

Do you think David Luiz should start for Chelsea? In what position?
