Porto 3 Roma 1 (aet, 4-3 agg): Telles hits last-gasp winner after VAR drama

Alessandro Florenzi surrendered a dubious punishment in additional time as Porto beat Roma 4-3 on total in the Champions League round of 16. 

Alessandro Florenzi conceded a controversial penalty in extra-time as Porto beat Roma 4-3 on aggregate in the Champions League round of 16.

Alex Telles scored a match-winning punishment with three minutes of additional time staying as Porto beat Roma 3-1 to secure a 4-3 total triumph and advancement to the quarter-finals of the Champions League. 

Roma took a 2-1 lead into the second leg after an unsatisfying triumph at Stadio Olimpico yet Porto leveled the tie when Tiquinho Soares scored from short proximity to put the hosts ahead on the night. 

Daniele De Rossi leveled from the punishment spot yet Moussa Marega made it 2-1 right off the bat in the second half before the diversion dwindled and went into additional time. 

A punishment shoot-out looked up and coming until Alessandro Florenzi's shirt pull on Fernando provoked a VAR interview and, after the ref indicated the spot, Telles ventured up and struck a late champ to send Estadio do Dragao into joys as Porto achieved the last eight without precedent for a long time. 

The outcome puts Roma mentor Eusebio Di Francesco's future in uncertainty with the club outside the main four in Serie An and no longer in conflict for any European or container titles, having endured a derby annihilation to Lazio last time out. 

Porto, in the interim, are the principal Portuguese club to vanquish Italian resistance in the Champions League since 2005 and Sergio Conceicao's men can keep on longing for European wonder while pushing for the Primeira Liga title.
