I arrived back in Argentina and a week after I had the offer from Arsenal. They called my agent and my family and I thought it was all about signing a new contract for my club in Argentina because they wanted to offer me one at the time, but it was actually to sign for Arsenal.
I remember the day me and my brother ate and my mum and dad did not. I know what they did for me to reach the top.
Thank you Arsenal. For me, I could not be happier to leave through the front door with the Arsenal fanbase supporting me and the club supporting me.
Bernd Leno's injury has changed my career. Other great goalkeepers - such as Iker Casillas - have got their big opportunities when the first-choice keeper was injured.
Sometimes when you make mistakes at big clubs you get punished. With Arsenal, people always seem to blame the defence for defeats. But I feel really safe behind them.
It's been up and down in my Arsenal career, to be honest.
I have been fighting 10 years to win trophies, not just to reach a final.
I was always progressing and pushing my career forward.
When you work hard, you are not going to be happy the whole time, you are going to have frustration, bad times in life.
When I went to Reading last season. I said to myself, 'This is my last loan.' My body was always tired at the end of the season from travelling and not knowing what I was going to be doing next, so I made that challenge to myself that it was my last loan and I had to do well.
My target is to consolidate my place with Arsenal and to reach the Argentinian national team as number one.
When I was playing for Reading, I got this feeling of being the No 1 - and I want that at Arsenal.
I remember for my Champions League debut against Anderlecht, my dad flew 27 hours to reach that game and he was crying all 95 minutes!
We came from a poor, poor family and for them to see me winning a trophy in front of 90,000 people and getting a medal would be something.
I said to my mum when I turned 18 and moved into my first flat in Enfield, 'I don't want to come back to my country with nothing. I want to make a career here.' I did not want to let them down.
I used to play up front so I always had the ability to play with the ball, even though I am 6ft 4in.
A second-choice goalkeeper can sometimes say: 'Oh, it's a lack of games, it's different when you train compared to when you play.' But there is no excuse if you do everything right.
I'm at an age now where I have a newborn baby and me and my wife want to settle. I'm tired of going on loan.
Obviously I love Arsenal. But it's time for me to make it there or go somewhere else.
My dream is to play for Arsenal, I've always said that and I believe I have everything that a keeper needs to play for Arsenal.
