The 33-year-old joined United from Real Madrid for £70 million in 2022 and has made 146 appearances in all competitions. He scored the opening goal in the 2023 Carabao Cup final victory over Newcastle United as Erik ten Hag's side finished third in the Premier League during his first season at Old Trafford. However, Casemiro was later referenced by new co-owner Sir Jim Ratcliffe, who stated that some players at the club were "not good enough" and "overpaid".
Among those clubs, Manchester United were initially seen as serious contenders. According to reports, Ruben Amorim had expressed admiration for Lewandowski's professionalism and experience. Amorim viewed the Polish striker as an ideal short-term addition, someone who could still perform at a high level while also mentoring United's younger attacking talents. However, the final decision was taken out of Amorim's hands.
