Manager Arsene Wenger expects his players to focus for the full 180 minutes as Arsenal prepare to host Monaco in this week's Champions League action.
The Gunners have been in scintillating form this year in the Premier League and the Frenchman will now hope his side can take their impressive form in tomorrow's Last-16 game against Leonardo Jardim's side.
But they have to be at their very best if they are to reach the quarter-finals of the competition for the first time in five years.
"What has happened in the last four years is that we have gone out twice against the winners of the competition," Wenger said.
"What we have learnt is that it was on [away goals] or because of one goal, which shows you that every single minute of these games will be absolutely massively important.
"We have gone out, yes, but only just. We want to stay in, even if it is [only] just.
"In the last four years we always came out frustrated because three times we conceded a goal at home in the first 30 minutes. That goal knocked us out. It was really tight.
"We have learnt from that and we can show that on Wednesday."
Meanwhile, the Frenchman says David Ospina will probably be in goal with Wojciech Szczesny again relegated on the bench.
"I worry about every single player in my squad and I want every single player to be happy but at the end of the day only 11 players can start the game," he said.
"That's the same for every single player. We have competition for places and that's part of our job. I don't think that's a special worry.
"He's [David Ospina is] fit. He trained."
