The Gunners went into last year's clash with the Bavarians off the back of an FA Cup exit to Blackburn, but the French boss feels his side are in a better frame of mind this timeArsenal manager Arsene Wenger believes his side are better mentally prepared to beat Bayern Munich than this time 12 months ago.
The Frenchman is preparing his side to face the reigning Champions League holders in a rematch of last season's round-of-16 tie, from which Bayern progressed on the away goals rule.
Arsenal had headed into that two-legged encounter on the back of a disappointing FA Cup defeat to Championship outfit Blackburn Rovers, but, a year later, now sit second in the Premier League and go into Wednesday night's game off the back of FA Cup victory over Liverpool.

"I think we are in a better mental shape than one year ago," Wenger said. "We'd lost to Blackburn in the FA Cup, which was a big disappointment.
"This time we won against Liverpool and we're determined to win the game (against Bayern). Since the start of the season we know we have to be 100 per cent. We believe we can do it but it's down to the quality of our performance."
Arsenal won 2-0 at the Allianz Arena last season, having been beaten 3-1 at home, and subsequently went on a 10-match unbeaten run to secure fourth spot in the Premier League.
Wenger believes the victory in Germany proves Arsenal can compete with Bayern, but is keen to avoid a repeat of last year's poor first-leg display.
He added: "It (beating Bayern) gave us belief to finish the season well. Since the start of the season we've done well, we're in a strong position.
"It's down to us how, from game to game, we can show the same spirit and focus we showed against Liverpool.
"It is of course important (not to concede at home); every minute counts in a game of that stature. We are of course conscious of that, we will try to start very strong."
