New Arsenal player, Pablo Mari, has promised to do his best for the London club after joining the side on loan from Flamengo on Wednesday.
The Gunners will reportedly pay £4million to the Brazilian club now and £8million to make the deal permanent.
Mari becomes Mikel Arteta’s first signing as Arsenal manager.
The 26-year-old is now looking to repay the faith Arteta has shown in him.
“I’m happy to be here today and to have signed for a big club,” said Mari at his unveiling on Wednesday.
“I’m going to do my best to help my team-mates and the club.
“I’m a very professional player. I like working hard every day to achieve objectives.”
He added: “One thing I can control is working hard on a daily basis to help my team-mates to win football matches and repay the faith that Mikel and Arsenal have shown me by signing me to play here, so that’s my main objective.
“I want to take it one day at a time and achieve big things at Arsenal.”
