The former Chelsea keeper, expected to play his last game for Arsenal in the Europa League final, said: “It will sound strange but I think generally at Arsenal there is not enough pressure. It sounds very strange but Arsene (Wenger) is a real gentleman.
As much as he hates losing, he stays a gentleman. If you lose, you win, you lose, you win he kind of carries on. That's something I've never experienced before. At Chelsea, at the times when we drew, it felt like a funeral in the dressing room. It was so bad, even drawing the game.
“If we drew against a big team at home, it was a funeral. It was like 'oh no, it is impossible we didn't win at home'. It is a different thing but it came from everywhere, the players, the coach.
“Since the start I was there, the pressure was there every game. I feel that every single time Arsenal needs to win, wins. It was very rarely in my four years when the team was in the position we really have to win, we won.
"I think generally we lose points every single time where there is not enough pressure. So, we went to Everton . You know you win, you go third, you lose you stay fourth. We lost. That week with Wolves , it was literally the same situation.
“There was always a cushion, there was always 'OK, it is not such a disaster'. This is generally where I believe we drop the most points, as soon as we think it is not such a disaster to drop points because we are still there, actually it didn't work."
He added: “We should probably create even more pressure on everybody because that would give people more to think about.
“It should come from everybody. I believe this is the only thing I think I would change. But everybody has different ideas and different feelings about it.
“This is something which is interesting to watch when you know that under the biggest pressure we always… we went to Napoli and everybody says 'oh, you are rubbish away they are brilliant at home'.
“And then you go 'how do you explain that?' If you are under pressure and you can't perform, you lose that game. But we didn't because the pressure was so high. You know you lose, you are out. You lose 3-1 at Rennes, you have to win at home, you win. So, the examples are there."
