Porto v Roma: Champions League last 16, second leg – live!

13 min: Porto are repeatedly attacking down the left flank, playing the ball into space behind Rick Karsdorp, who is being isolated and outnumbered on his first Champions League start. Once they get past him, they’re sending in crosses to Moussa Marega and Tiquinho Soares.

10 min: Porto have dominated these opening 10 minutes and Alex Telles goes close, firing into the side netting from a tight angle with a left-footed shot from inside the penalty area. Moments later, Tiquinho Soares tries a shot from the edge of the area that is blocked by Kostas Manolas.

9 min: Felipe tries to pick out Porto right-back Rick Karsdorp with a diagonal cross-field pass, but it’s intercepted.

6 min: Porto attack down the right. Eder Millitao sends a cross whistling in from the right flank, which Roma goalkeeper Robin Olsen plucks from the sky with Marega lurking ready to pounce on any scraps.

4 min: Diego Perotti gallops up the inside left with Edin Dzeko making a run ahead of him. Perotti attempts to play the ball past Felipe and into the path of his team-mate, but his pass his poor and the defender stretches to intercept.

3 min: Not having played with three at the back for some time, Roma are looking a little uncomfortable early doors.

1 min: Roma get the ball rolling, their players wearing their usual kit of tyrian purple (no, really) shirts and shorts with gold socks. Porto’s players also wear the colours with which they are most accustomed: blue and white striped shirts, blue shorts and white socks. Roma are immediately under the cosh, conceding a corner from which Jesus Corona volleys narrowly high and wide from the edge of the penalty area.

The coin-toss: Daniele de Rossia and and Hector Herrera exchange pennants and the Porto captain wins the coin-toss. Roma will kick-off.

Not long now: The teams assemble in the tunnel at the Estadio do Dragao, before marching out on to the pitch led by Turkish referee Cuneyt Cakir. They line up either side of the match officials and stand to attention for the Champions League anthems. Kick-off is just a couple of minutes away.

Fun fact: Iker Casillas, who probably wouldn’t be human if he hadn’t been reduced to paroxysms of mirth by the evisceration of his former club Real Madrid by Ajax at the Bernabeu last night, makes his 175th appearance in the Champions League tonight. This game will mark the 37-year-old goalkeeper’s 60th appearance in the knockout stages.

Referee: Cuneyt Cakir (Turkey)

Some team news: Roma manager Eusebio Di Francesco has made a total of six changes from the side that beat Porto in the first leg, with Diego Perotti, Robin Olsen, Juan Jesus, Rick Karsdorp, Ivan Marcano and Steven Nzonzi all coming in to a side that could line up in a very defensive 5-2-3 formation. For Porto, Moussa Marega and Jesus Corona come into the side, replacing Fernando and Yacine Brahimi, who started the first leg.

Not to be outdone by his opposite number, Porto’s coach also spoke of the importance of the group over the individual. “The collective is what counts,” he said. “Our confidence is from our day-to-day work, not from any individual player. We need to be effective in attack, but also in defence. There’s no need for a battle-cry: the game is in our hands.

Patience, he insisted, would be a virtue. “We need to win the game, but not so quickly,” he said. “We have to be at a good level defensively; Roma have the third best attack in Serie A. Balance will be essential to get the win.”

Conducting his pre-match press conference yesterday, Roma’s manager was asked how his side needed to approach this game. “We need to focus on the collective and not on individuals,” he said. “The selection decisions will be made based on a lot of factors. It’s vital that we go out there with players who are clear-headed, focused and ready to show what the real Roma is like.”

Asked about his team’s defeat at the hands of Lazio at the weekend, he conceded that his team are down at the moment. “We’re having a tough time,” he admitted. “The derby has damaged morale, but this is a bit of a game of life or death. Every player in the squad knows they need to be ready to play at any moment and no-one knows the team we will pick. I want to decide, in the end, by looking into the players’ eyes and seeing who is most ready for battle.”

Porto manager Sergio Conceicao is likely to welcome back Moussa Marega following his absence from the first leg through injury. The Mali international completed 90 minutes against Benfica over the weekend following his return from a thigh injury. Striker Vincent Aboubakar remains a long-term absentee, having been ruled out since September with ruptured knee ligaments.

With his side fifth in the Serie A table and travelling to Portugal on the back of a hiding in the Rome derby last weekend, Roma manager Eusebio di Francescocould lose his job if his side fail to progress tonight. Despite being forced off with injury in that game, the first leg’s two-goal hero Nicolo Zaniolo is available for selection tonight, as is central defender Eusebio di Francesco, who missed the first leg through injury. Cengiz Under and Javier Pastore are both sidelined with muscle injuries.

The Estadio do Dragao is the venue as Porto entertain Roma with a place in the quarter-finals up for grabs. The tie is finely poised, with Roma leading 2-1 from the first leg on the back of two quick-fire goals from 19-year-old midfielder Nicolo Zaniolo. With 11 minutes to go, Adrian Lopez bagged a potentially precious away goal for Porto. Both sides come into tonight’s game on the back of big derby defeats, Porto having lost 2-1 at home to Benfica in the O Clássico on Saturday, while Roma got stuffed 3-0 in their Derby della Capitale with Lazio. Roma are slight favourites to advance to the next round, but this tie is on a knife-edge and extremely difficult to call. Kick-off is at 8pm (GMT) but stay tuned for team news and build-up in the meantime.
