Gretar Steinsson admits he didn't enjoy the pressure of last season's relegation battle with Bolton Wanderers.
"It's something to tell the grandchildren in years to come: how we got away with it, how we got out of it. It was unbelievable, but I don't ever want to go through anything like that again.
"It was mentally hard for the players, the staff and for the fans but it's something we will learn from. We can't let that happen to us again."
The Iceland defender added: "I feel I am established now, not just a 'winter buy', so I'm really looking forward to the start of the season.
"I can't wait. At the moment it's all about getting ourselves prepared. Being physically fit is important, but we have to be mentally ready for the start. We just can't let the same things happen to us that happened last season."
