The Arsenal boss hailed his side's mettle as it came from behind to take Wigan to penalties and book a place in the FA Cup final before boldly predicting a top-four finish.
The Gunners boss watched his side come from a goal down against Wigan to seal their place in the FA Cup final after triumphing 4-2 on penalties.
And Wenger quickly switched his attention to the Premier League where his side was overtaken by Everton on Saturday after their 1-0 win at Newcastle.
Arsenal now trails the Toffees by two points, with both sides playing 33 matches, but the Frenchman was bold in his assertion that the Gunners can reclaim a top four position.
Speaking to reporters at Wembley, the Frenchman stated: "If we win our remaining games I think we will finish in front of Everton so we need to focus on the Premier League now."
The Gunners continue to chase their first piece of silverware in nine years and an FA Cup final against Hull or Sheffield United lies in wait for Wenger, who was unsurprised by Wigan's quality on Saturday.
He added: "We're feeling relieved because we were under pressure but I expected a difficult game.
"The difference between winning and losing is very small and this game has shown it again."
Wenger reserved special praise for goalkeeper Lukasz Fabianski - who looks increasingly likely to leave the north Londoners in the summer - after a matchwinning display in the shootout.
"Fabianski has shown what a good goalkeeper he is today," Wenger said. "He put us in a good position in the penalty shootout."
