It's normal to have early difficulties when you get a new manager with a new concept.
When you have bad moments, you have to improve. You have to become stronger to deal with it, and I believe I have become stronger.
If you are at United, you need a manager with a winning mentality. We had that with Ferguson. Mourinho has it. He wants to win every game.
Titles are what I crave.
I consider all aspects of being a goalkeeper as fundamental in the development of the side as a whole.
Football is football, and a thousand things can happen.
Normally, I focus on my job and focus on trying to help my team and trying to improve every training session and try to be as a good as I can.
It would be great to have more Spanish players at Manchester United.
In training, the players would deliberately hit high balls into me and barge into me so I'd get used to that side of the English game. I actually enjoy the physical side of it now.
Manchester United are a great club, and being associated with them is a great compliment for me, but Atletico are also great.
When you do things wrong, even a couple of mistakes, the press has the right to criticise. Much more so when you're a goalkeeper - who remain in the spotlight forever.
Getting to the national team is very complicated.
When I'm on the pitch, I only think about helping the team and doing well.
As a goalkeeper, it is a challenge to face Messi.
The biggest thing for me is that I've managed to work through some difficult times, and those moments always make you stronger. It makes you a stronger person and a better player.
As a goalkeeper, I'm well aware that any mistake can be magnified by the fans. But it's true that here at Manchester United, there's added pressure.
At the end of the day, this is football, and it's quite normal for anyone to go through difficult moments - and it's something you can learn from.
In the Under-21s, I played good football for several years, trying to play the same game as the best and with some very good players.
I think I have improved a lot since I arrived in England.
The fans of Manchester United are one of the best in the world. I felt the support of them from the first day, and I am really happy with them.
