Arsenal manager Arsene Wenger believes that his side have their best chance to beat Barcelona in the upcoming Champions League pre-quarters clash, and called on the Emirates Stadium club to find 'a good balance between attacking and defending' to claim the victory.
The Spanish giants trounced Arsenal in the finals of Champions League in 2006 before knocking them out of the tournament in 2010 and 2011 as well.
Wenger insisted that they would never get a better chance of knocking out Barcelona and, therefore, urged Arsenal to put their best foot forward in the game,the Mirror reported.
The French manager further backed Alexis Sanchez to rediscover his form, adding that he hopes the forward would be completely tuned in the upcoming match.
Arsenal, which are third in the Premier League standings, will lock horns against Barcelona in the first-leg of the last -16 Champions League tie at Emirates Stadium on Wednesday.
