"But to be that you have to win trophies, and that's something we haven't done yet and what we're trying to do this season".
Liverpool are firm favourites to advance to a semi-final against Barcelona as they go into the match with a 2-0 lead from last week's meeting at Anfield, and having triumphed 5-0 at the same stadium in the same competition last February.
Conceicao admits they will be facing a formidable test, but he is relishing the chance to go toe-to-toe with the five-time champions of Europe. Porto are a good team.
"We played better this season".
And the visitors made them pay by scoring with their first shot on goal when Sadio Mane slid in to turn home Mohamed Salah's ball towards goal.
The reds, despite their 2-0 lead, didn't look their usual calm selves but all that changed in the 25th minute with Liverpool's first attack of the game.
Bernie Sanders' Tax Returns Show He's Now A Millionaire
A liberal website, ThinkProgress, earlier this month posted a video about what it called "Bernie's millionaire problem". In 2014, the year before he launched his first presidential campaign, Sanders had an adjusted gross income of $205,271.
"That's a nice compliment, and we get those compliments by playing good football over a sustained period of time", said Milner.
"We'll try to use the result [at Anfield] and go there confident". Hopefully, we can show it again.
Klopp said: "We have more experience, that is clear, we are not too experienced but we have had hard away games". They have comfortably won their last three games, against Bayern Munich and these two versus Porto, but doing that against Barcelona - or rather, doing that against a team with Lionel Messi in it - is a different challenge entirely.
Milner agreed: "The result a year ago was a bit of a false result".
"Some of the talk in the media when we got this draw [that this was an easy tie for Liverpool], I would have taken it as pretty disrespectful if I was a Porto player".
Liverpool then netted two later goals to put the icing on the cake and march onto the semifinals of the Champions League. I am looking forward to it and it's brilliant, but not tonight. They didn't manage the goal but they certainly caused Liverpool's defence some anxiety. I think everybody tried it so far and nobody can really do it.
And in this situation, Milly certainly wasn't having a bar of it and insisted that they needed to win something before such plaudits came flowing towards the side.
