Having spent the entire summer trying to engineer a move to Bayern Munich, Poland international Robert Lewandowski now says he wants to make his final season at Borussia Dortmund a successful one.
The 24-year-old failed to push through his dream move to the European champions but now says the affair is over and that he is dedicated to trying to help his current employers reclaim the Bundesliga title from his future ones.
"This summer I was disappointed and bitter but the differences have been erased and the subject is closed. What counts now is titles," he told Sport Bild magazine in an interview published Wednesday.
However, there is no chance of him going back on his decision.
"This will be my final season at Dortmund," he added.
Lewandowski did gain one concession to his contract which runs out in May 2014, negotiating a pay rise from 1.5 million euros ($2 million) a year to five million euros ($6.7 million) for his final 10 months in Dortmund.
The Warsaw native has even set his sights on wrenching all three trophies Bayern won last season from the Bavarian giants, who also claimed the German Cup on top of their Champions League and Bundesliga successes.
But Lewandowski said he expected "a huge battle right to the end of the championship".
And he added that Borussia are "better armed than last year" despite the sale of star playmaker Mario Goetze to Bayern.
"With (new signings) Pierre-Emerick Aubameyang, Sokratis and Henrikh Mkhitaryan, we have a better squad than last year," he added.
Dortmund started the season with two straight victories with Aubameyang netting a hat-trick in their opening 4-0 win over Augsbourg before Lewandowski himself scored an own goal in the 2-1 success against Eintracht Brunswick last weekend.
