Micheál Martin commented on the matter while visiting the midlands this week.
The Taoiseach hasn't ruled out reappointing Barry Cowen and Robert Troy to Cabinet.
Longford-Westmeath TD Troy resigned as Junior Business Minister two weeks ago, following controversy over his failure to declare ownership of a number of properties.
While his party colleague, Laois-Offaly's Barry Cowen was sacked as Agriculture Minister in 2020 after it emerged he received a drink driving ban in 2016.
Speaking in Offaly, Micheál Martin and Deputy Cowen both commented on the likelihood of the midlands TDs returning to ministerial office:
