Lewandowski, who was 24 at the time, had expressed his desire to play for Manchester United and meet their legendary coach, Alex Ferguson. He told a reporter that he had indeed agreed to join the team.

However, Dortmund's decision to keep him meant that they could potentially earn more money from his skills. Lewandowski acknowledged that he had said yes to Manchester United, but ultimately stayed with Dortmund.

Looking back, Lewandowski wonders if playing in the Premier League could have been a missed opportunity. Nevertheless, he is content with his career choices, having played for Bayern Munich, Dortmund, and now Barcelona.

Lewandowski emphasized that his decisions were made with the goal of achieving his own ambitions, and he doesn't feel like he missed out on anything.
