FT | Roma beat Porto 2-1 at the Stadio Olimpico. Zaniolo starred for the hosts, scoring two second half goals. His first was a good finish inside the area. The youngster passed the ball into the net for his second after Dzeko hit the post. Lopez got a vital away goal for Porto late on, but they were unable to find an equaliser.
'87 | Nzonzi feeds Dzeko for a Roma counter and the striker plays in El Shaarawy. Militao gets back to push off El Shaarawy and end the attack. Hernani rides a challenge on the right and crosses. Florenzi calmly chests the ball back to Mirante.
'83 | Dzeko makes another good run behind the defence and looks to have an opportunity to create something before he is closed down and forced backwards. Nzonzi is introduced for Pellegrini to add fresh legs into midfield.
'79 | GOAL! Roma - Porto 2-1. Adrián! Soares' sliced shot drops to Lopez in the Roma box. He is under no pressure and puts it past Mirante to get Porto a crucial away goal.
'74 | GOAL! Roma - Porto 2-0. Zaniolo! Dzeko breaks into the Porto half, creating space for a right-footed shot from 25 yards. Casillas cannot get to the ball and it bounces off the post. Zaniolo remains calm to pass the ball into an empty net.
'70 | GOAL! Roma - Porto 1-0. Zaniolo! Zaniolo quickly moves the ball onto his right foot and creates space to shoot under pressure from Telles. His shot goes across goal and past Casillas into the far corner.
'68 | Both teams are arguing on the touchline because Brahimi was down again when Roma were attacking. Conceicao wanted Roma to put the ball out of play and is furious that they played on.
'64 | Brahimi is down holding his left ankle. Danilo Pereira puts the ball out of play. Brahimi is being helped off the field by his team-mates and will receive treatment from the physio on the sideline.
'60 | Pellegrini has a go from distance! The midfielder has been far more involved in the second half and is given time on the ball from range. He eyes up a shot and drives a right-footed effort. Casillas saves relatively comfortably, but Roma are finding more space in the attacking third.
'56 | Telles whips a corner at the near post and Danilo Pereira wins it, but his guided effort goes wide of the far post. Herrera finds Militao in space on the right, giving the right-back time to cross. His delivery is poor, though, and it is easily cleared.
'52 | Zaniolo drifts infield with the ball at his feet and plays a short pass to Cristante. The midfielder spins on it and smashes the ball goalwards. Casillas reacts quickly to punch it clear.
'48 | Dzeko is fouled by Felipe near the halfway line after another excellent touch to bring a long pass under control. Casillas makes an almighty mess of a cross, causing chaos in the Porto box. The visitors scramble to clear it before Roma can take advantage.
HT | Roma and Porto played out a goalless first half at the Stadio Olimpico. Dzeko came closest to opening the scoring when his right-footed, close range effort hit the post, but neither side have created much so far.
'44 | Fernando plays the ball up to Brahimi as Porto try to build a counter. Florenzi reads the situation well and steps in for an interception. Pellegrini is down after being caught by Soares' hand in a challenge. The contact is minimal but the Roma man is receiving treatment from the physios.
'40 | Fazio carries the ball out of defence and drops a pass onto Dzeko's foot to the left of the penalty area. Dzeko takes it down beautifully, cutting onto his right and unleashing a fierce shot goalwards. Unfortunately for the hosts, the shot cannons off the near post and goes to safety.
'36 | Florenzi is lucky to avoid a foul throw as he gives the ball to Zaniolo, who is fouled around 30 yards from goal. Pellegrini swings the free-kick into the area, but it's a few inches too high for Manolas.
'32 | Mirante is forced into action! Soares gets a shot off on the turn after Fazio gave away possession. The Porto striker doesn't get enough on it, and Mirante saves comfortably.
'28 | Pellegrini registers the first shot of the match! Kolarov crosses first-time from the left, forcing Casillas into a weak clearance. The ball falls to Pellegrini, who strikes from the edge of the area. It is easily saved.
'24 | Brahimi dribbles past a lunging De Rossi on the halfway line and makes his way into the final third. Roma do well to get back behind the ball and force Porto to build from the back again.
'20 | Roma get themselves in a mess at the back after a sliced De Rossi clearance. The ball loops into the air and other attempts to clear it are poor. It ends when Otavino miscontrols and Fazio boots the ball up the field.
'16 | Cristante is unimpressed with the decision to give Porto a throw. His complaints are brief and Roma quickly win the ball back in midfield. Danilo Pereira carries the ball into midfield after a hard challenge on Zaniolo. The Porto midfielder hesitates in possession, losing the opportunity for a counter.
'12 | Porto run a training ground routine and hit an aerial pass for Herrera to strike first-time. He is quickly closed down and does not get a shot off. Roma break quickly after the failed set piece and Dzeko delivers a dangerous ball which Felipe nearly puts into his own net.
'8 | Kolarov plays a one-two with El Shaarawy as he overlaps and fires a low cross towards Dzeko. Casillas dives to claim it. De Rossi plays a first-time pass to Dzeko in midfield and the Roma striker is fouled.
'4 | Porto are pressing high early on. Fazio and Manolas cannot find an easy pass into midfield. El Shaarawy dances past Militao in the area after an error from Felipe. He cuts the ball back, but Porto scramble to clear it before the hosts can get a shot off.
