The Serie A outfit came into the encounter leading 2-1 and they almost fell behind inside the opening five minutes when Alex Telles volleyed over the crossbar, before the Porto attacker hit the side-netting 10 minutes later.
Di Francesco, 49, was part of the last title-winning Roma team as a player in 2001 and took over the club in the summer of 2017.
"Di Francesco will always be the coach who took Roma to the Champions League semi-finals after who knows how many years, and he deserves credit for that", said De Rossi.
Carlos Ghosn posts bail as court rejects appeal
Mr Ghosn's lawyer, Junichiro Hironaka , insisted that this client would stick to the restrictions of his release. There is also no plea deal mechanism that would allow Ghosn to agree to lesser charges for a lighter sentence.
"On behalf of myself and everyone at AS Roma, I'd like to thank Eusebio for his work and his commitment", team president Jim Pallotta said in a release.
Francesco's sacking comes just a day after the Serie A giants were bundled out of the Champions League in the round of 16.
Corona crossed from the left and Marega easily got away from his marker and side-footed the ball into the roof of the net from two metres to level the aggregate score at 3-3.
An additional half-hour was required to settle an encounter that looked to be heading for a shootout before Telles tucked home from the spot on 117 minutes after a tug on Fernando by Alessandro Florenzi was spotted upon review.
He was sacked last week by Premier League strugglers Fulham after only 17 matches in charge.
