Lukasz Fabianski has an explanation for his fine form towards the end of the season - he feels more relaxed on the pitch.
The Polish goalkeeper returned to the Arsenal first team in March and contributed to five wins in his five appearances before a rib injury forced him out of the side in April.
I think it's wrong to think during the game. It's just about focus, being vocal, being ready, being switched on and stuff like that
Fabianski's first game back was a daunting Champions League trip to Bayern Munich but he came through it confidently - keeping a clean sheet in the Allianz Arena.
After that game Arsène Wenger said Fabianski had undergone "a complete mental transformation". The 28-year-old admits that he has made strides in that area of his game.
"It's all in your head," he told Arsenal Player. "There are a lot of things [that make a good goalkeeper] but the main thing is just the head.
"Especially for a goalkeeper, you've got a lot of time to think during the game. I think it's wrong to think during the game. It's just about focus, being vocal, being ready, being switched on and stuff like that. I know that with my abilities, I will be good.
"But I don't think I'm a changed person or anything like that," he added. "Obviously I worked during the time I was out for a longer period with a few different injuries. I really worked hard on different aspects of my game and I put in a lot of hard work with the help of a few of the coaches that we have at the Club.
"Maybe that has helped me. For example, during that time I could look back at the things in the past and tried to change it or embrace some things or push it even harder - don't have any handbrakes.
"Maybe that's the way the boss sees it now, that I went through a total mental transformation. I know what I am capable of. I know my strengths, I know my weaknesses and I know how to deal with it so that's the main thing for me."Copyright 2017 The Arsenal Football Club plc.
