                                       2





         This Amendment No. 13 amends the Statement on Schedule 13D, dated
October 25, 2001, as amended (as previously amended, the "Statement on Schedule
13D"), filed by UniCredito Italiano S.p.A., a company organized under the laws
of the Republic of Italy ("UniCredito"), 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.

         UniCredito, Pirelli, Edizione Holding, IntesaBci S.p.A. (now Banca
Intesa S.p.A.) ("Intesa"), Olimpia S.p.A. ("Olimpia") and, as discussed in Items
4 and 6 of Amendment No. 6 to the Statement on Schedule 13D, Hopa S.p.A.
("Hopa") are members of a group with respect to the Telecom Italia Shares. This
Amendment constitutes a separate filing on Schedule 13D by UniCredito in
accordance with Rule 13d-1(k)(2) under the Securities Exchange Act of 1934, as
amended.

Item 3.  SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION

         On October 15, 2003, Olimpia purchased 266,300,000 Telecom Italia
Shares for an aggregate purchase price of approximately euro 597.7 million,
representing a price per share of euro 2.2445. The transaction occurred in
connection with the simultaneous sale by Olimpia of its entire holding of
504,825,562 Telecom Italia 2001-2010 convertible bonds for a price per
convertible bond of 1.172 euro plus accrued interest, and involves a nominal
cash settlement of approximately euro 3,000 to be received by Olimpia. A copy of
a press release concerning the transaction issued by Olimpia on October 15, 2003
is filed as an Exhibit to Amendment No. 23 to Pirelli's Schedule 13D, dated
October 17, 2003, filed as Exhibit 38 to this Schedule 13D and incorporated by
reference herein. Approximately 492 million of the Telecom Italia 2001-2010
convertible bonds that were sold by Olimpia on October 15 had been (until the
time of their sale) pledged with Intesa, Banca di Roma, Unicredit Banca
Mobiliare S.p.A. and Unicredit Banca D'Impressa S.p.A. pursuant to the Pledge
Agreement filed as Exhibit 16 to the Statement on Schedule 13D. In substitution
for those bonds, 259,797,136 of the Telecom Italia Shares that were purchased by
Olimpia on October 15 have been pledged pursuant to the Pledge Agreement.

Item 4.  PURPOSE OF TRANSACTION

         The Olivetti Merger (as that term is defined in Amendment No. 8 to the
Statement on Schedule 13D) became effective on August 4, 2003. A copy of a joint
press release concerning the Olivetti Merger issued by Olivetti and Telecom
Italia on July 29, 2003 is filed as an Exhibit to Amendment No. 21 to Pirelli's
Schedule 13D, dated August 12, 2003, filed as Exhibit 37 to this Schedule 13D
and incorporated by reference herein.. The Olivetti Merger resulted in the
merger of Telecom Italia with and into Olivetti and the surviving entity
adopting the name Telecom Italia S.p.A. (The surviving entity from the Olivetti
Merger will henceforth be referred to in the Statement on Schedule 13D as
"Telecom Italia").

Item 5.  INTEREST IN SECURITIES OF THE ISSUER.

         According to Amendment No. 21 to Pirelli's Schedule 13D, dated August
12, 2003, following the consummation (and as a result) of the Olivetti Merger,
Olimpia beneficially owns 1,190,715,823 ordinary shares of Telecom Italia,
representing approximately 11.575% of the total number of shares of that class
reported to be outstanding by Telecom Italia. By virtue of its ownership of 8.4%
of the outstanding shares of capital stock of Olimpia, UniCredito may be deemed
to beneficially own all shares of Telecom Italia beneficially owned by Olimpia.

         (a) As of September 23, 2003, UniCredito and its subsidiaries held as
pledgee, with a right to vote, 13,752,510 Telecom Italia Shares, representing
approximately 0.13% of the total number of outstanding Telecom Italia Shares.


                                       3



         (b) UniCredito has sole power to vote or to direct the power to vote
13,752,510 Telecom Italia Shares that have been pledged to UniCredito in
connection with loan transactions entered into in the ordinary course of
UniCredito's banking business.

         (c) Except as disclosed in Item 3 of the Statement on Schedule 13D and
other than pledge transactions entered into in the ordinary course of
UniCredito's banking activities, UniCredito has not effected any transaction in
Telecom Italia Shares during the past 60 days.

         After giving effect to the acquisition of the 266,300,000 Telecom
Italia Shares referred to in Item 3, Olimpia holds 1,457,015,823 Telecom Italia
Shares, representing approximately 14.16% of the total number of outstanding
Telecom Italia Shares.
