MILAN, Nov 12 (Reuters) - The controlling shareholder of Italian soccer club AS Roma said on Monday it had been informed by a third party of possible interest from an unnamed U.S. investor.
Shareholder Italpetroli said it had not been contacted directly or indirectly by the potential investor.
An unsourced report in Italy's Corriere Economia on Monday said the owners of English soccer club Liverpool are buying up stock in the Italian side.
Rules on soccer club ownership are strict, however, and generally prevent one group owning more than one team.
American sports tycoons George Gillett and Tom Hicks agreed to buy Liverpool for $340 million in February.
Roma's share price has been on the rise for several months, with the club previously saying in September it knew of no reason for the rally other than strong financial results and good performances on the pitch.
