Goals from Richard Dunne and Darren Bent had given the visitors a comfortable advantage, but two Robin van Persie penalties and a fortunate Theo Walcott effort ensured the north London outfit made the draw for the fifth round.
The French coach hailed his team’s resolve after the game, and is eager to continue the cup run.
“We wanted to stay in the cup,” Wenger told ESPN.
“I felt 2-0 was very harsh for us at half-time, but it was a question of scoring the 2-1 goal and keeping our structure and not doing anything silly.
“Fortunately we got an early 2-1 [goal],” he stated.
Arsenal will be one of the favourites to win the tournament now, as both Manchester clubs have been eliminated, and Wenger knows his team have a chance.
“It is an opportunity, but you can see today how difficult the games are. But we played at home, we wanted to qualify and we did it,” he continued.
Wenger went on to state that it is unlikely that any new faces will join the club before the transfer window closes, but he feels that injured Jack Wilshere is in good spirits.
“I cannot say nothing will happen, but it would be a little bit of a miracle now. For us the biggest thing is to get our players back.
“I have spoken to Jack today. His morale is strong. Hopefully we will have good news,” he concluded.
Arsenal will now travel to take on either Sunderland or Middlesbrough in the fifth round.
