Wednesday's Champions League second-leg clash between Porto and Roma promises to be a fascinating fixture.
The tie is wonderfully poised following a 2-1 win for Eusebio Di Francesco's side in the Italian capital last month.
Roma will be grateful for that advantage, for they have an appalling away record in this competition. Indeed, the Serie A side have won just two of their last 19 Champions League ties on their travels.
Porto, then, will be positive that they can overturn that first-leg deficit on their own patch. Sergio Conceicao's side an even money (2.0) chance to claim a vital victory on Wednesday night.
Roma are chalked up as a 53/20 (3.65) chance to march into the quarter-finals in style, with victory in Portugal. A draw would be enough to see the Serie A side through and also offer 53/20 (3.65) that this match ends level.
Porto's Moussa Marega missed the first-leg of this tie through injury. The Mali striker, who has scored five Champions League goals this season, is fit to face Roma this time around. Vincent Aboubakar, however, remains a long-term absentee for the hosts.
Edin Dzeko, who has also scored five goals in this competition thus far this term, will spearhead the visitors' attack. Turkish winger, Cengiz Under, is a doubt for Di Francesco's men.
Roma have conceded 15 goals in their last five away matches in all competitions. The Italians, however, have scored 10 goals in those matches - including three on three separate occasions.
Porto have scored in each of their 21 home matches in all competitions this season. Conceicao's side, though, surrendered top spot in the Portuguese league with a 2-1 home defeat at the hands of Benfica on Saturday.
There is certainly plenty of potential for goals in this game. There have been at least four goals scored in six of Porto's last seven Champions League ties on home soil. SportPesa offer 9/5 (2.80) that there are more than three goals scored on this occasion.
Conceicao's charges have won five of their last six Champions League ties on home turf. For Porto, then, home advantage could well prove pivotal on Wednesday night.
Roma will surely travel with trepidation given their terrible record on their travels in this competition. Di Francesco's men, too, suffered a demoralising 3-0 derby defeat against Lazio on Saturday.
Quote (2.0) for Porto to win Wednesday's tie could well represent good value for punters.
