Wenger admits coming days decisive for Arsenal
The Gunners face German giants Bayern Munich on Tuesday after today's FA Cup fifth round tie with Championship outfit Blackburn.
He said: "If we get past them, then why should we not go further and win it?
"I believe we have a chance to beat them.
"When we went to Real Madrid a few years ago they had Zidane, Beckham and Raul and we beat them. It's just down to us to believe we can do it."
