Porto coach Sergio Conceicao has told his players to be patient when they attempt to beat Roma and reach the last eight of the Champions League.
The Serie A side won last month's first leg in the Italian capital 2-1 and are 12/1 to win the second leg of the round of 16 tie 1-0 while Porto are 11/10 to qualify for the quarter-finals.
Roma are currently fifth in Serie A after losing 3-0 to city rivals Lazio on Saturday while Porto are second in the Primeira Liga table after losing a crunch game at home to Benfica 2-1 on the same day.
Conceicao said: "We're ready for a tough game. We know, regardless of form, that Roma concede a lot of goals.
"However, we must be ready to face a Roma side that will defend their lead strongly. This is clear, we are aware of that.
"Our plans could change during the match though. We must try to win, but without haste.
"We know Roma's strong points, as they have the third best attack in Serie A. They have great players and are strong tactically. Keeping things balanced will be key."
Porto to score in both halves on Wednesday can be backed at 13/8.
