The following season, Lombardo won the Supercoppa Italiana in 1991 against previous Serie A champions A.S. Roma, as well as the Serie A title. In fact, Lombardo also played in the Sampdoria side that reached but narrowly lost the European Cup Final in overtime to Cruyff's F.C. Barcelona under Vujadin Boškov. He also enjoyed a successful season in 1993–94, where he scored 8 times in Serie A, and 5 in the Coppa Italia, enough to lead his team to a second Coppa Italia win in 1994, where he scored twice in the final.
