With [Samuel] Eto'o, I talked a lot about his great career and how I could become a better player.

It was Thomas Tuchel's first season as coach and I played centrally always. The whole team had a great year, one that I enjoyed a lot. Our style has changed a bit, from trying to score within five seconds to a more calm and in some regard more educated style of play. We try to find the right moment - and then we explode.

The fans of Borussia Dortmund are truly amazing. It is hard to describe what you feel when you play in front of them, the atmosphere they create not only on the yellow wall with its 25000-something fans jumping up and down a full 90-plus minutes of every game, no matter the score or the opponent.

I've played in France. There, in many matches everybody is already happy if he can secure a point. Here, in Germany? Forget it! Everybody wants to win. The last-placed team in the standings would take any match with the ambition to win it. That makes it so hard, even for the best teams in the league.

I've worked really hard on getting into the box more and being closer to the goal, which I think has brought real benefits to my game. It's definitely improved my goal scoring.

I always set myself new goals. I always want to do better than I did in the past. I always want to achieve things I never achieved before.

Most of all I hope the tournament [The 2017 Africa Cup of Nations] will help unite our people [in Gabon]. My wish is to celebrate a big party all together.
