David Luiz accepted responsibility for Arsenal's loss to Manchester City, hinting he should have sorted his future before his side's season resumed.
The Brazilian defender endured a nightmare outing after coming on in the first half at the Etihad Stadium on Wednesday as Arsenal suffered a 3-0 Premier League loss.
David Luiz was at fault for Raheem Sterling's opener before being sent off after dragging down Riyad Mahrez early in the second half, Kevin De Bruyne converting the penalty, with Phil Foden sealing City's win late on.
The 33-year-old David Luiz, who is coming out of contract, accepted the blame for Arsenal's defeat in their first game back after the coronavirus-enforced break.
"It's not the team's fault, it was my fault, I take the decision to play," David Luiz told Sky Sports.
"I should take another decision the last two months but I didn't. I think the team did well, especially after with 10 men, the coach is amazing, all the players did amazing, it's just my fault."
With so much speculation surrounding his future, David Luiz suggested an earlier decision on his contract may have helped his performance.
"A different decision, to try to decide my future, to try to decide as early as possible but I didn't," he said.
He added: "I don't what to use that as an alibi or excuse, it's my fault and that's it."
Mikel Arteta wants to keep the defender at the club, and David Luiz said his desire was to extend his stay at Arsenal beyond one season.
"I'd love to be here – that's why I continue to train hard, that's why I came here today, that's why I try to do everything," he said.
"That's why I'm here put my face, that's why I said to all the players nobody had to speak, it's me, I have to show my face and be here.
"I want to stay, the coach knows, the coach wants me to stay so we are waiting for the decisions."
