Cape Town - Arsenal midfielder Aaron Ramsey says their Wembley against Chelsea success proves they have finally figured out how to defeat their main rivals.
Ramsey revealed that Wenger believes a more cautious approach, which they adopted to close out the Chelsea match - prompting Mourinho to criticise Arsenal for abandoning their attacking philosophy - is the key to defeating the big guns.
"I think we've learnt over the years how to play against the bigger teams now. Sometimes you have to sit in and invite them on and get them on the counter-attack," Ramsey said.

"Chelsea have done that against us ever so well in the past so we sort of used different tactics to get the result."
After winning last season's FA Cup final against Aston Villa in swaggering style and finishing strongly in the league, Ramsey sees no reason why Arsenal can't win the title for the first time since 2004 - provided they avoid the kind of sluggish start that proved so costly last year.
"It was important for us to carry on the good form we are in at the moment," Ramsey said.
"You can definitely sense something has clicked, but we have to get off to a good start because we saw Chelsea have a good start last season and they stayed top for basically the whole season.
"If we do that we will have a good chance. We have a great team, so we are just excited about what this season can bring for us."
