           This Amendment No. 54 amends the Statement on Schedule 13D,
dated August 9, 2001, as amended (as previously amended, the "Statement
on Schedule 13D"), filed by Pirelli S.p.A. (which, as reported in
Amendment No. 21 to the Statement on Schedule 13D, subsequently merged
with and into Pirelli & C. S.p.A., a company incorporated under the laws
of the Republic of Italy), and, commencing with Amendment No. 1 thereto,
Olimpia S.p.A., a company incorporated under the laws of the Republic of
Italy, with respect to the ordinary shares, euro 0.55 par value per
share, of Telecom Italia S.p.A., a company incorporated under the laws
of the Republic of Italy.  Capitalized terms used in this Amendment
without definition have the meanings ascribed to them in the Statement
on Schedule 13D.

           Pirelli & C., Olimpia, Sintonia S.p.A. (which, it publicly announced
on March 9, 2007, has replaced Edizione Holding in various shareholders
agreements relating to Olimpia) and Sintonia S.A. (which, according to Sintonia
S.p.A.'s public announcement, is the new name of Edizione Finance) are members
of a group with respect to the Telecom Italia Shares. This Amendment constitutes
a separate filing on Schedule 13D by Pirelli & C. and Olimpia in accordance with
Rule 13d-1(k)(2) under the Securities Exchange Act of 1934. Pirelli & C. and
Olimpia are responsible solely for the information contained in their separate
filing, except that information contained in the Statement on Schedule 13D
concerning any director or officer of Olimpia nominated by Sintonia S.p.A., its
predecessor Edizione Holding or Sintonia S.A. has been provided by the
nominating person or by such nominee director or officer.

ITEM 5.    INTEREST IN SECURITIES OF THE ISSUER

           On April 19, 2007, Pirelli Finance (Luxembourg) S.A. ("PFL") entered
into two separate share forward agreements with Banca Caboto S.p.A. and Intesa
Sanpaolo S.p.A., respectively, under similar terms and conditions, whereby PFL
agreed to sell and immediately repurchase an aggregate number of 134,957,885
Telecom Italia Shares on April 19, 2007 (the "effective date"). Under each share
forward agreement, Banca Caboto S.p.A. and Intesa Sanpaolo S.p.A. assume the
risk of any increases in the price of the notional number of Telecom Italia
Shares covered by the agreements between the effective date of each transaction
and the valuation date of July 24, 2007, subject to any early termination.

           Reference is made to the equity swap transaction between Olimpia and
UniCredit Banca Mobiliare S.p.A. ("UBM") described in item 5 of Amendment No. 7
to the Statement on Schedule 13D. On April 27, 2007, the parties settled the
transaction in cash at an average price of Euro 2.3578 per Telecom Italia Share
without the physical delivery of securities.
