Granit Xhaka feels justified over his decision to leave Arsenal for Bayer Leverkusen a year ago.
The Switzerland midfielder helped Bayer win a first ever Bundesliga title in his first season with the club.
He said, "We want even more. Not only this year, but obviously we want to play at the top in the coming years.
On leaving Arsenal, Xhaka said: "For me it wasn't a step back, but rather two steps forward. Because I had the precise feeling, discussing with the coach (Xabi Alonso) and with (sporting director) Simon Rolfes, that something special could happen here in the next few years."
