The striker, 27, is now aiming to shoot down Arsene Wenger's Gunners in the Group H clash at the Emirates.
Matheus said: "The key to the match for us will be to give our all and take advantage of the opportunities we get on the counter-attack.
"I love Arsenal's incredible attacking style, but I don't intend to suffer from it.
"I intend to enjoy it. Scoring at the Emirates would be an incredible moment for me to remember."
