Xhaka was part of the team that defeated Chelsea in the FA Cup final at the national stadium last season, and has spoken of his desire to play at Wembley again.
"It is always special to play there," the Swiss international told the Evening Standard. "I played my first senior game for Switzerland there. In my first year here we won the FA Cup there.
"We can't do that again this season but our aim now is to win the other two cup competitions we are still in.
"We played well at Chelsea in the first leg and have a big chance to win the return match and reach Wembley. Obviously, the cups are the quickest way to win trophies."
Man City booked their place in February's final by securing a 5-3 aggregate win over Championship side Bristol City on Tuesday.
