Spot kick savior Lukasz Fabianski believes Saturday's win can be a turning point in the Gunners season.
The Poland international's two saves in the penalty shoot out proved decisive as Arsenal progress into the FA Cup final by beating Wigan 4-2 on penalties after the sides were tied after 120 minutes.
The 28-year-old, who has been man of the match in four of the Gunners five FA Cup ties, hopes the momentum and feel good factor created by the Wembley win can have an impact on the Gunners five remaining league games this season.
"I do think that Saturday's win could prove pivotal for our season.
"The main thing is that it means we are winning again, which is a very good habit to develop.
"I always hoped that I would eventually get the opportunity to change the bad Wembley memories into good ones
"Recently we have had a bit of a run which was not great and this hopefully puts an end to it and gets us back on track. So it was probably vital for us."
Arsene Wenger has said previously that Fabianski's place in the FA Cup team was decided a long time ago. However that hasn't stopped some fans debating whether his compatriot Wojciech Szczesny should get the nod ahead of him for next month's final.
Fabianski though feels he's done enough to earn his place in the Wembley showpiece.
"I would be disappointed if I did not get to play in the final.
"I think that I have done enough during the course of this cup run to merit getting picked to play in the final.
"We were all acutely aware of needing to end the season pursuing a major trophy. But we cannot lose sight of the equally important need of qualifying again for the Champions League by finishing in the top four in the league.
"If we do that first, then we can go into the cup final in a really positive frame of mind. And hopefully enjoy the experience of a Wembley final without forgetting that we must win it."Arsenal will face Hull City on May 17 to decide who will win the FA Cup.
