David Luiz believes his new team has the ability to “shine” like previous Arsenal sides, adding that he wants to help the club fight for Premier League titles.
“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.”
