David Luiz has always been a confusing player and nothing has quite summed that up like the last couple of weeks.The Brazilian was absolutely terrible against Tottenham Hotspur as Chelsea suffered a 3-1 defeat, with Luiz looking off the pace, lacking concentration, and regularly finding himself out of position.But then he goes and puts in a showing like Saturday against Manchester City where he was possibly the best player on the pitch.Luiz looked solid defensively against the Premier League's best attack and started the move for N'Golo Kante's goal with a sensational cross-field ball.To top it off, he sealed Chelsea's 2-0 with a brilliant header from a late corner.Those two performances will likely be fresh in the mind when the club make their upcoming decision on Luiz's future.The 31-year-old is about to enter the final six months of his contract but Chelsea have a club policy that they don't offer multi-year contracts to players over 30.Luiz, however, wants a longer deal.Maurizio Sarri says he wants to retain Luiz but Chelsea are far more reluctant to break from their policy for the defender.As for what the Chelsea fans would like, support appears to lean quite heavily towards the club's stance.You can check out some of the reaction below:

It's a real sign of just how inconsistent Luiz has been that even in the wake of an outstanding performance, Chelsea fans are near-unanimous in not giving into his demands.

There have clearly been far too many worrying performances over the years, enough that potentially losing him on a free is considered okay.

As for what Luiz should do, he's probably right in wanting a longer deal at his age and he can likely get one outside of the Premier League.

Despite his heroics on Saturday evening, this might be the season that Luiz and Chelsea finally go their separate ways.
