David Luiz wants to help Arsenal win Premier League titles.

The Brazilian, signed from Chelsea this summer, had a poor game in Saturday's 3-1 loss to Liverpool at Anfield.

But the result hasn't diminished Luiz's belief that the Gunners can win major honours.

"This club has the potential to shine like it has shone in the past. We have a lot of talent, we have players with a lot of quality," Luiz said.

"I came here with the ambition to fight for the Premier League title, I want to fight for other competitions also.

"It was like that at the other clubs I have been at but it was not always easy, there were difficult moments.

"I am going to try to do my best every single day and try to help everyone to believe in this because I think this club can believe a lot because it has a lot of potential.

"Football is about the end not the beginning and we are going to have to try to fight to the end."
