The Gers host the Portuguese giants at Ibrox on match-day four of the group stages and know a victory will give them a massive opportunity of reaching the knockout stages of the competition.
The two teams drew 1-1 in Oporto a fortnight ago, with Rangers only denied a late win via an Alfredo Morelos header thanks to a brilliant last-gasp save, and Gerrard has been quoted as saying the pressure will all be on Porto come kick-off tomorrow night.
But speaking to the media this evening, Conceicao was having none of it, saying via the Sun: “I don’t know if that is a bit of a bluff from Rangers. Whether we are favourites or not, we’ll see how we perform.
“The opinion of Steven Gerrard is his opinion. Managers all have their own opinions.
“But historically we are used to the Champions League and Europa League more than Rangers so we are maybe more at home in European competition.
“Now we have to prove that. We know these games aren’t easy. It’s never easy. Rangers are a very competitive team.
“Rangers will draw on the aggression and competitiveness needed to succeed at this level.
“We have improved on some key things in the past couple of weeks.
“But we have a strong team and a strong mentality. We need to be strong because it’s always difficult away from home, in front of fans who are so passionate.
“The home fans make a big difference. We know that because our own fans make a difference. I wouldn’t say I was surprised by Rangers in Porto.
“Rangers did some good things in that first match. Porto, on the other hand, had some deficiencies and some things we could have done better.”
After facing Porto, Rangers will travel to Rotterdam to face Feyenoord before hosting Young Boys of Bern in their final group fixture.
Do you think Gerrard will lead his side into the knockout phase, and how far can they go in the competition this season?
