Opinion is entirely split over whether David Luiz was a good signing for Chelsea.
At £32 million, making him football's first £100 million defender, there's an argument to be made that Antonio Conte has paid over the odds for a player renowned for making costly errors.
On the other hand, Luiz is versatile and recently insisted he is willing to play wherever his manager tells him to.

Only time will tell whether his return is money well spent.
But for Chelsea legend and Sky Sports pundit Ray Wilkins, Luiz is a nonsensical signing and "a penalty waiting to happen".
Speaking on Sky Sports, in quotes relayed by the Metro, he said: "We are coming up to Christmas and he loves giving presents away.
"He is a penalty just waiting to happen, especially as a central defender.
"Don't get me wrong, he is a very talented footballer, but he is not a centre-half as far as I’m concerned.
"He is a holding midfield player or a midfield player. He just makes very, very rash decisions and poor decisions as a centre-half. I don't understand why they brought him back into the fold."
Wilkins' concerns were epitomised by Luiz's dreadful display for Paris Saint-Germain during a 3-1 defeat to Monaco in late August, for which he was rated a 2/10 by L'Equipe.
The Brazil international was hauled off by manager Unai Emery in the 62nd minute having received a yellow card and given away a penalty.
However, it would seem Conte has every intention of using Luiz as a centre-back when the Premier League restarts this weekend.
"I think David Luiz is a centre-back," the Italian told ChelseaTV, "he's played a lot of games in that position.
"I know sometimes he's played as a central midfielder but in my mind, the idea is to utilise him in the right position which, for me, is centre-back. He's played with Chelsea previously and he will bring a good personality."
As for Luiz - well, he's happy to play just about anywhere.
He also told ChelseaTV: "I started playing three at the back with Vitoria in Brazil, but it doesn’t matter where. I want to help and when I am in the team I am there to try to help.
"The coach is an amazing coach, he understands a lot of tactical things and I know he chooses every match the best line up.
"If he needs to play three, four or two, it doesn't matter, I am there if he wants me to play. In different positions I am available."
