Francis Coquelin says Arsenal must impose themselves from the very first whistle of Saturday's FA Cup semi-final at Wembley.
The Gunners have won 16 of their past 18 matches and are heavy favourites to progress against Championship side Reading.
However, Coquelin - who played against the Royals earlier this season while on loan at Charlton - says they will have to make a fast start to the match.
"Whether you are in the Championship or the Premier League, in a game like this the team who puts the most pressure on and creates the most chances will win"
“You know the FA Cup, you don’t know what to expect - any team is ready for it and it is always a tough game at any stage,” he told Arsenal Player.
“A semi-final at Wembley will be even tougher. We need to be ready and start on the front foot. Hopefully we can do that and win the game.
“I remember a tough game [against them for Charlton]. We won 1-0, but to be honest I don’t think we really deserved it.
“They put a lot of pressure on us, they have Pogrebnyak up front who is a big threat, and on the wings they have great players as well. We know it will be a tough game, it is a semi-final and the league you play in doesn’t matter.
“Whether you are in the Championship or the Premier League, in a game like this the team who puts the most pressure on and creates the most chances will win. If everyone is focused, we know we can get a good result.”
