MILAN, March 10 (Reuters) - Telecom Italia (TIM) will disclose more details over the expected trajectory of its debt and cash flows, two sources said on Sunday, after the company's board discussed last week's share price plunge following a strategy day.

At the board meeting, Finance chief Adrian Calaza offered to resign after TIM shares on Thursday posted their worst daily fall on record, the sources said.

However, the board did not take Calaza's offer into consideration, and backed instead the management team's decision to attempt to reassure investors by disclosing more financial details, the sources added.

Milan-listed shares in TIM plunged 24% on Thursday hit by worries about debt and cashflow after the former phone monopoly issued a three-year outlook under a new structure following the planned sale of its fixed-line network.

The fixed-line network is TIM's main asset.

The sources said TIM would provide the further details before markets opened on Monday. (Reporting by Elvira Pollina; Editing by Valentina Za)
