The Dane scored a hat-trick which, along with goals from Marouane Chamakh and Gael Clichy, guided the Gunners to a quarter-final visit to Manchester United. It was a perfect response to the north London club's Carling Cup final defeat by Birmingham, as well as the loss of Robin van Persie to injury. Bendtner told ESPN: "I think Arsenal is about the team and team performances and I think we showed that today." Of the visit to Old Trafford, Bendtner said: "We know it is going to be difficult but we look very much forward to that game but we look very much to Sunderland on Saturday." Arsenal manager Arsene Wenger was pleased with the way his team bounced back from their defeat against Birmingham. He said: "It was a good response, we took the game in a serious way. It was good to win the game. "We are on a fantastic run. On Sunday we lost a game in special circumstances." The Frenchman revealed Tomas Rosicky - who limped off injured - had "a little concussion from an accidental elbow" but expected to him to be "all right". Wenger welcomed the goalscoring efforts of Chamakh and Bendtner, especially given Van Persie's absence. "We cannot afford other injuries and for them to score is a bonus for us as we have so many games." As for the rest of the campaign, Wenger said: "It will be interesting until the end of the season. "Every game now is a cup game - we had one tonight and will have one on Saturday." Orient manager Russell Slade was not downhearted after the game and paid tribute to the Gunners. He said: "It was a difficult night for us. Chances were few and far between. "Arsenal were in the mood tonight and made life difficult for us. "They played some wonderful football and we tried to live with that." Slade thought it was not of benefit to the east London side to be playing the Premier League team after their heartbreak on Sunday. "That is something I said before the game," Slade said. "They are a group of internationals who are very focused and disciplined and their attitude tonight was spot-on."
