“I am very, very happy about the new agreement,” revealed the 26-year-old.
“There are not many clubs out there who have such a large fanbase and there are also not many clubs who have been able to do what we have achieved in the last two league seasons.
“It is great to remain a player of this big club Borussia Dortmund.”
Blaszczykowski captained Poland at the 2012 UEFA European Football Championship, starting three matches and tallying one goal and one assist for Biało-czerwoni.
In addition, the former Wisła Kraków star totaled seven goals and 11 assists in 40 appearances in all competitions for Die Borussen last term.
Prior to finalising his new contract, Blaszczykowski had been linked with a move to the Merseyside earlier this summer.
With that said, inking a new contract does not mean that the player is off the transfer market.
On 2 July 2012, Thiago Silva signed a new five-year contract with Serie A runners-up AC Milan. Less than two weeks later, the Brazilian was on his way to the French capital to compete a move to Ligue 1 club Paris Saint-Germain for a reported transfer fee of 42 million euros.
Nonetheless, Borussia Dortmund general manager Michael Zorc is happy to have tied Blaszczykowski to the Signal Iduna Park until June 2016.
“We are delighted to have agreed new terms with Kuba (Blaszczykowski),” said Zorc.
“Kuba has shown in the most recent Bundesliga season why he is such an important player at our club. Kuba also has the Dortmund emblem very much stored in his heart.”
Walcott talks in progress
Arsenal winger Theo Walcott has suggested that his contract negotiations are ongoing despite rumours linking him with a move away from the Emirates Stadium, Sky Sports understands.
Walcott was the Gunners’ second most productive player in 2011-12, behind only star striker Robin van Persie.
Ironically, both players have been linked with moves away from north London this summer, with Juventus reportedly preparing to offer RVP a club record deal worth £190,000-a-week.
Now then, it would be much easier for Arsene Wenger to replace Walcott instead of Van Persie, with teenage wingers Alex Oxlade-Chamberlain and Ryo Miyaichi seemingly destined for stardom.
Like RVP, Walcott has just one year left on his current contract. That means both players could leave the Emirates Stadium on free transfers next season. In other words, more bad news for Arsenal Football Club.
Will Arsenal risk getting nothing in return for two of their biggest assets?
