Osvaldo Fabian Grimberg (Hebrew: פביאן גרימברג; born 6 February 1962) is an Argentine former professional association footballer who was part of the 1988–89 championship squad at Maccabi Haifa.
In 1988, Maccabi Haifa decided to bring in Jewish players from Argentina since they would qualify as immigrants and not as transfers.[1] The Jewish Agency paid for all travel and even some living expenses for new immigrants, saving the club money.[1] Grimberg was brought in under these circumstances, along with Fabian Lagman and Patricio Sayegh.[1]
