Arsenal's Santi Cazorla has said that he expects Reading to be tough to beat tomorrow.
The winger believes that the Gunners will have to work harder against the Royals, who are in the relegation battle, than they did against Swansea City before the international break.
The Spaniard told Arsenal.com: "Swansea had already qualified for the Europa League after winning the League Cup and you might notice, with teams like that, they're a little looser, that same pressure isn't there.
"But it can go either way. It can be beneficial or work against you. But I think, from now, every match will be very difficult.
"In the end, we're all fighting for something important, some teams to get into Europe, some to get into the Champions League, others for the title, others to stay up."
Arsenal have won four of their last five games in the Premier League.
