I can't worry about external factors, I have to focus on myself.
Shinji Kagawa
Football is what I do best.
I know and I am very proud that in my home country Japan and all over Asia millions of people are interested in BVB and follow us on a daily basis.
I have gained good experience but at the same time had hard times as well.
If you play well and consistently, it opens up a lot of opportunities.
In the Champions League you need a certain level of perseverance, strength, dedication to scoring over 90 minutes.
I will aim to become a No. 10 who can score goals. Just like Lionel Messi does for Barcelona.
When playing for Japan, it means that I carry my country on my shoulders and I feel a different kind of pressure as I am expected to do more when playing for Japan.
In every match, my only aim will be to win.
My aim is to deliver results.
I am always willing to score.
I can only say that I've found a wonderful spot at Borussia Dortmund, where I can play football. I feel comfortable here.
When I watch the Champions League, we see great clubs.
I can't retire without going to Spain.
I have played in Dortmund and Manchester United, no matter what country I go to, I will not be afraid.
It would be good to play in the Premier League.
I have to stay positive and play hard.
I respect Manchester United, but I have respect to Dortmund as well.
There were a lot of things that you cannot experience in other places. I felt that Manchester United are a big club with fans and attention all over the world.
Those who can keep achieving results are the big players at the big clubs. If you cannot get the results, you just can't play and move away.
It was great to win the title with United.
You have to believe in yourself. If you don't, things can go wrong both on and off the pitch.
Being positive and believing in yourself is important, not only in football but also in improving as a person.
Cerezo often have a bad season after a good one.
After moving to the Premier League, I've realised that I need to limber up and strengthen my body trunk.
The Spanish league is my favourite. The attacking mentality suits my style.
From my own personal experience, I can tell you that things I achieved in the J2 league meant a lot to me.
Since Japan is little known in football in the world, we want to play good football and make a huge impact so that we can make the world realise the presence of the Japan football team.
Personally, scoring goals creates confidence and I gain the mental stability and get poised from it.
In my time here, I've seen that Borussia Dortmund has developed steadily. We have become German champions and played in the Champions League.
Nothing changes if we spend all our time worrying about the teams above us, so all we can do is win our next match.
My value can only go higher if I can perform well in the Champions League.
It is hard to win in Asia.
If you don't concentrate during a national team match you can just as easily get injured, so I want to make sure I can focus.
I know that not everything is easy.
It's easy to play with joy when everything is going well.
Sendai is the place that helped me build my basement.
If I'm chosen for the Asian Cup, then I must help the team win. That's the bottom line.
The Asian Cup is an important tournament.
I've repeatedly emphasized how comfortable I feel in Dortmund.
The really crucial thing here at BVB is that everyone works together so hard as a team. I'm a part of that, and I'm delighted I've been able to contribute to our good results.
I'd like not only to test myself against Barcelona, but top teams from the other leagues.
If you play well in the Champions League you get your name out there.
BVB with its incredible fans has grown in my heart.
I never lost a game against Bayern Munich until Pep Guardiola arrived. He made them better.
Klopp never wanted us to get carried away. He never wanted us to think of ourselves as champions, even though we were top of the league. He wanted us to focus on ourselves, not to listen to what people were saying about us. It was all about the next game and only the next game.
There was a lot of passion with Klopp, I felt that most in the dressing room before games. He always had a big smile. He hugged every player. I loved his attitude - he was never nervous. He gave us confidence.
Football has given me so many opportunities in life and now I want to play my role in supporting others through the game.
Common Goal is quickly growing around the world and I'm proud to help lead the movement forward in Japan.
I've been fortunate enough to have football lead me all over the world... If there's one constant I've witnessed throughout the journey, it has to be passion.
