Arsenal manager Arsene Wenger has insisted that it is not "impossible" for his side to clinch an unlikely victory over Bayern Munich in the Champions League.

The North London outfit have a hefty task of overcoming a 3-1 deficit from the first leg at the Allianz Arena tomorrow in order to reach the quarter-finals of the elite competition.

"It is not mission impossible," Wenger told the club's official website. "It can be done, but first of all you need 100% commitment, attitude and things to go your way. But usually football goes your way when you have the right attitude.

"There is a kind of [feeling of] 'let's really play with freedom'. Let's start strong. We have to create doubt in their mind and you only do that if you have a real go."

Meanwhile, the Frenchman has confirmed that midfielder Jack Wilshere will be sidelined for three weeks with an ankle injury.
