Doubt looms over David Luiz's £34 million return to Chelsea but he can prove his critics wrong by hitting the ground running against Swansea City on Sunday.
A centre-back by trade, the Brazilian has been brought in by Antonio Conte to add competition, steel and versatility at the back.
Indeed, Luiz is also capable of playing as a defensive midfielder.

Where Conte decides to deploy his summer signing - if anywhere - remains to be seen but what's apparent is the 29-year-old is willing to play wherever he is asked.
In an interview with Chelsea's official website, Luiz revealed how he doesn't have a preferred position.
He said: "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."
So, what exactly is Luiz's best position?
There's an argument to be made that it's alongside N'Golo Kante in central midfield given his tendancy to roam and shoot from range.
His frailties at the back might also see him played further forward, where any potential mistakes won't prove as costly. It's hard to envision Conte dropping John Terry or Gary Cahill to make room for Luiz, either.
Regardless, the Brazil international just seems happy to be back at a club where he won the Champions League in 2012 and the Europa League a year later.
"It was my decision [to rejoin Chelsea], yes," he added. "I really wanted to come back because I spent an amazing time here.
Premier League glory is what Luiz is aiming for this season.
"It is time to do it! And I hope it will be this year. I am working hard for that and this is our goal this season."
