Rocco B. Commisso, the billionaire founder and chairman of the cable provider Mediacom, is expected to complete a deal to purchase the Italian soccer club A.C.F. Fiorentina in the coming days. Commisso, who was born in Italy but moved to the United States when he was 12, is also the chairman of the New York Cosmos, and has been investigating the possibility of buying an Italian team for some time. He was left frustrated last year after failing in a takeover bid for A.C. Milan, a European soccer heavyweight that had fallen into a financial crisis.

Should a deal for Fiorentina go through, Commisso would join a growing list of American owners in Italian soccer: Milan is now owned by the Elliott Management hedge fund, A.S. Roma is backed by the billionaire James Pallotta, and there are North American-linked ownership groups at Bologna, in Serie A, and Venezia, in Serie B.
