The details are outlined by El Mundo Deportivo, but the coronavirus impact on football’s finances and Barcelona’s valuation of €25m for each player is said to have made the deals complicated.
Roma are said to have directly approached sporting director Eric Abidal about deals for both, in the knowledge that Barcelona are open to sales this summer.
Firpo has appeared in 16 matches for the Catalan giants this campaign but remains very much the understudy to long-term left back Jordi Alba at the club.
The Dominican-born player failed to convince Ernesto Valverde nor his successor Quique Setien – who managed him at Betis – that he was worthy of a regular first-team slot.
Left wing-back Firpo only joined the Blaugrana from Real Betis last summer but a recent report in Diario Sport suggests he could be allowed to leave this year.
