In undoubtedly one of the more surprising moves of transfer deadline day, David Luiz is back in the Premier League with Chelsea, and people are still trying to figure out if the deal makes any sense.
The Brazilian became a cult hero during his original stint at Stamford Bridge, helping the team to win the Champions League, Europa League and F.A. Cup before leaving for PSG in 2014.
However, he was also prone to the odd howler and was widely seen as a weak link during his final few months at the club, meaning Chelsea fans may be worried about his second coming.
According to one highly respected French journalist, they have every right to fear what lies ahead.

"He’s been a liability for PSG more than anything else,” Le Parisian journalist Julien Laurens told BBC Radio 5 Live after Luiz's shock £30 million move had been confirmed on Wednesday night.
"Everybody remembers the game he had against Barcelona and Luis Suarez, who nutmegged him twice, in the Champions League quarter-final and humiliated him at the Parc des Princes.
"He hasn’t improved at all since leaving Chelsea. He’s probably coming back a worse player than when he left."
Hardly words to inspire confidence amongst Chelsea fans that Luiz has managed to eradicate the lapses in concentration and decision-making that plagued his time at Stamford Bridge.
'He had some shockers'
Laurens wasn't done there either and, speaking from experience having watched Luiz at PSG on a near weekly basis over the past couple of seasons, he wasn't exactly complimentary about the player Antonio Conte is getting back.
"Well yeah, they (PSG) almost got their money back, two years after he left, for a player who’s two years older.
"I’ve watch him pretty much every weekend since he joined PSG, I can hardly remember four games where he was actually good, or very good maybe. He had some shockers.
"PSG couldn't believe their luck and I think first of all they tried to keep him because they had no other options and then they thought ‘the money’s too good, we can’t turn that down, it’s impossible’."
Skip to 1:10 for one example of Luiz's PSG "shockers"...
After failing to land a string of centre-back targets over the past few weeks, there's no doubt that Luiz was a long way down Chelsea's list of potential arrivals.
And, with John Terry and Gary Cahill still linking up in the starting XI, it isn't clear how much game time the Brazilian will actually get during his second stint.
Nevertheless, there will likely be a time when one of the above is unavailable to Conte this season. The question then is, can he really rely upon Luiz to step in and keep things solid?
According to Laurens, absolutely not.
