According to unofficial information, the Portuguese coach had been approached by Brazilian top club Flamengo.
Chairman Kulesza announced on Twitter that he refused to cooperate with Sousa's departure, writing that "he wanted to terminate the contract with the Polish Federation by mutual consent because of an offer. This is extremely irresponsible behaviour, contrary to the coach's previous declarations. That is why I firmly refused." Cezary Kulesza tweeted.
51-year old Sousa, former player, later coach among others of Leicester, Fiorentina and Bordeaux, took over the Polish national representation in January 2021.
This has not been a greatly successful season for the Poles. Poland lost 1-2 to Hungary in the team's final World Cup qualifier in November. The Poles did not qualify directly for the 2022 World Cup in Qatar, securing a spot in the playoffs in March for the tournament.
One of the reasons for Sousa's departure is said to be the criticism fielded against him in Poland.
Poland are currently No.23 in the FIFA rankings, moving up one spot on the latest list, released in October.
