Criticism for the forward has followed the announcement of his impending move to Bayern Munich, but it is BVB that must shoulder the blame for his exit.
He was forthright in his response. Will you be announcing your deal with Bayern in January? "Yes," he said. "Because then I can officially sign the contract."
These comments come in the wake of an interview with Rzeczpospolita late in the summer in which he was heavily critical of Dortmund's decision to deny him a move in the summer window. The club promised to sell him to Bayern, he said. The club lied.
Therefore, it was not so much an open secret as an overt fact that the Poland striker would be signing for Pep Guardiola's team next summer and doing so amid acrimony. Coming in the immediate aftermath of Mario Gotze's move, as it does, there has been, unjustly, some villainy detected in Lewandowski's decision to jump ship. But it's not his problem that Gotze moved before he did.
Nor is it his problem that he was low-balled by Dortmund when the club opened talks about a new contract at the end of a brilliant 2011-12 season for him. He owes the BVB nothing.
He only ever signed one contract with Dortmund, the one which was handed to him upon completion of his move from Lech Poznan in 2010. It was worth about 1 million euros per year for a duration of four seasons, a sum that was fair for a young striker who had not yet proven himself in one of Europe's better leagues.
After 18 months of that deal, Dortmund realized it had more than a bargain on its hands and tried to tie him to longer terms as goal followed goal.
"We are disappointed with the offer. I've said this to the president," his agent Cesary Kucharski told Revier Sport at the time. "A player of this class should be among the highest-paid footballers at Dortmund."
There was a willingness, initially, to negotiate, to stay. Dortmund missed its chance.
The club paid only 5 million euros for Lewandowski and he established himself in the lineup, becoming one of the most feared forwards in the world. He was worth many times more than that in the summer when Bayern was battering down Hans-Joachim Watzke's door to do a deal.
It was seen as admirable at the time that Dortmund withstood Bayern's attempts to take away its top forward. But in truth Dortmund chased folly with folly all throughout Lewandowski's time at the Westfalenstadion. It was a lesson in how not to treat a player, undervaluing him in contract negotiations, failing to cash in at a time when his price was high, being left with a dissatisfied player in the ranks.
Player power has never held more of a grip than it does currently. It is a huge risk for teams to not only fail to meet salary expectations on the part of key performers but also to be so negligent as to allow contracts to run towards expiry. Moreover, it is wrong to lie to them.
In the case of Lewandowski it was always the intention of the player and his agents to achieve a move to Bayern. Kucharsky and the player's other representative, Maik Barthel, have always made it known in the press that their client's over-arching ambition, and by extension their own, was Bayern.
Dortmund's intransigence played right into their hands. So while this summer Lewandowski looked destined to move, it needn't have been as such. This is a mess entirely of Dortmund's making. The club failed to make a key asset an offer he could not refuse. Instead, it insulted him and put in motion a sequence of events that rendered the move to Bayern unavoidable.
Now the team is left in a situation whereby it has had to offer him a 500 percent pay increase for the last season of his deal just to motivate him enough to take the field. He has not played like a hotshot so far this season despite Dortmund's strong start. He has looked tetchy, temperamental and a little out of sorts.
Betrayal on the part of Lewandowski? Not a chance. There is nothing amiss with his timing. He was asked a question and answered it honestly. He has held his part of the deal. He's playing, scoring goals, turning up for training and seeing out his contract. And, more than that, he's telling the truth. Dortmund may fancy itself as one of Europe's elite teams but it has not behaved like one here. Big clubs know how to keep their players happy.
