I had three very successful years in Germany with Borussia Dortmund, but I had the opportunity to move to one of the biggest clubs in the highest-profile league in the world.
I was always taught by my father to challenge myself and to continue to evolve in my career, and I saw the move to Manchester United as an opportunity to grow as a player and as a person.
It was definitely not the salary that made me join Manchester United; I went for football reasons - for the history of the club, the league, the fans, and the coach because he is one of the best in the world.
I like to win the difficulties, because when you win the difficulties, it makes you stronger, so I'm trying to do everything to come up to a new level.
If you play football, you have to try to do the maximum, so I'm always doing the maximum for myself because, after my football career, I want to sit down and think I did something good.
I always wanted to become a football player, and I thank my parents, as they helped me so much to realise this dream. They always supported me on my path.
Not so many Armenian players are given the chance to play in the Champions League, and this is really important for me, because I want to do everything to impress the children who are watching me playing.
Every person has to keep in mind that they can grow up and reach the top, no matter where they are born, whether it's in Russia, in Ukraine, in Europe; they've still got the opportunity to show their talent and the culture of their people.
Coming to Manchester, maybe I didn't show all my potential, but in every game, I'm trying to do my best because it's very important for me, the fans, and the club. Maybe in some games it doesn't work, but I still keep working and trying to improve.
Everything comes from your mind. You have to push yourself to get things going in your direction. If you are stubborn, nothing will help. If you are sad, nothing will help. You have to keep positive and to work very well for your next chance.
I'm trying to do everything with my family members, my friends, who are watching me every day, every game I am playing, so they are trying to help me to say what I did wrong and what I did well, and I try to improve myself.
I don't think I will play every game, depending on the tactical situation, depending on the opponent, but I will do everything to try and help the team.
