Bayern are 20 points clear in the Bundesliga and heavy favourites to progress, but the Ivory Coast winger believes that his side can produce a "miracle" in Munich.
He told the club's official website: "We know it is not going to be an easy match. They are one of the best teams in the world with good players all over the pitch, so we are expecting a tough game, but we must remain confident.
"We scored at Emirates Stadium against them, and you just never know, a miracle can happen. If we score an early goal it will put them under pressure. We just need to keep positive and give everything we have. We all know anything can happen in football.
"Personally, I still believe we can make it, I know it will be difficult, but I still believe in us. We are going through a tough period at the moment, but there is still a really good spirit with this group of players. Just because we lost the first match at Emirates Stadium, we will not give up."
Arsene Wenger's side have lost three of their last four games in all competitions.
