Much has been made of Arsenal’s dip in form in recent weeks, with Wenger’s side coming into this tie in sixth place on the Premier League standings.
Their humbling by Bayern Munich in the Champions League comes alongside a number of league losses, although they last overcame Middlesbrough 2-1 the last time out.
The FA Cup though remains one shining light, with wins over Preston North End, Southampton, Sutton United and Lincoln City making this their third FA Cup semi-final in the past four seasons – and 11th for Wenger – that includes six final wins.
Manchester City came through a recent league blip of two draws and a loss, as well as their exit from the Champions League, to record two wins, over Hull and Southampton, and edge away from Manchester United in fifth place.
Their fallen FA Cup opponents were West Ham, Crystal Palace, Huddersfield Town and Middlesbrough. They have won this famous competition five times, with their last success in 2011, where they beat Stoke City in the final.
Ahead of the game, Wenger said: “Going to Wembley is always a special experience,” Wenger told Arsenal Player. “When our supporters go to Wembley, I think it’s a special occasion in their life. You want them to come out there and be pleased by having a positive experience.
“On our side, we want to win the game. It’s important that you go into big games and feel you can win them. That’s something that’s vital in the players’ heads, for their careers, for their confidence and for their self-esteem. It’s something special.”
City boss Pep Guardiola added: “For all clubs, titles are so important.
“Of course, titles help to win confidence that the club is able to do great things. Winning titles gives you the self-confidence to say we’re good enough to compete. Whether we win the trophy or not, nothing will change in terms of expectations for us.
“I would like to win the FA Cup so my players realise how good they are. At the moment, they don’t realise how good they are, but winning titles helps this. When you win a title, it’s a lot of stress and pressure, and if you handle that the next time it will be a little bit easier. That’s why it’s important.”
