Bayern Munich midfielder Javi Martinez has admitted that he is surprised by the club's success this year.

The Bavarian outfit won the Bundesliga title, the Champions League and the DFB Pokal in Jupp Heynckes's final season as coach.

Martinez, who moved to Germany from Athletic Bilbao last summer, has said that Bayern's achievements surpassed his expectations.

"I definitely knew that the team was capable of greatness, but the fact that at the end of the season we managed this historic triumph was certainly a surprise," Martinez told TZ.

"It will be very difficult to repeat all that success in the coming season. This campaign we won three trophies and we are entered into the history books. In Germany, no side had done this previously.

"It is going to be difficult, but we will do everything that we can to celebrate again next year like we have this season."

The Spanish international made 43 appearances for Bayern last season.
