Borussia Dortmund star Jakub Blaszczykowski has revealed he rejected the opportunity to join Manchester City, preferring to remain part of Jurgen Klopp's project at the Bundesliga club.

The Polish international has played an integral role in the Dortmund side that have challenged at the summit of German football over the past three years, whilst earning rave reviews for his performances in the club's march to last season's Champions League final.

Collecting plaudits for his industry and commitment in addition to his creative qualities from a wide position, the Poland international was awarded with a new five year contract in May, ignoring reported interest from Juventus and Manchester City.

When quizzed on his lucrative offer from the Premier League side, Blaszczykowski explained how he saw little reason for moving to the Etihad Stadium, unequivocally reaffirming his dedication to Dortmund.

"Borussia prevail. As I mentioned, we have a splendid team, coach, fans and exciting prospects," Blaszczykowski told Polish newspaper Przeglad Sportowy.

"Money can always be decisive. I took into account many factors. It was important that my family feel happy in Dortmund. We know the city, the people, we have friends. "

Blaszczykowski's contract renewal in spring will have been welcomed by Dortmund fans who had only recently learned of Mario Gotze's move to Bayern Munich, when the Bavarian giants met the attacking midfielder's €36m release clause.

The blow of losing perhaps their most prized asset was intensified when Dortmund lost to Bayern in last season's Champions League final at Wembley, but Klopp's side have struck the first blow as the two German giants recommence their tussle in the 2013/14 season.

Two goals from Marco Reus helped his side confine Pep Guardiola to defeat in his first competitive game in charge of the Bundesliga champions as Dortmund beat their rivals 4-2 in the German Super Cup.

Klopp's side have been handed a further boost after Robert Lewandowski reassured the club he is prepared to give his all for the club in what is likely to be his last season at the Westfalenstadion.

The Polish striker, whose contract expires next summer, had been persistently linked with a summer switch to both Manchester United and Bayern, but he eased the concerns of Dortmund supporters with his promise to focus solely on success with this current employers.
