In Rome, there has been mention of “una rimonta” - a comeback.

But no one really believes Daniele De Rossi’s side will throw this tie away at the Amex, do they?

Even the example which has been quoted in Italy was only about coming from three goals down.

And it was secured with the help of the now obsolete away goals rule.

“As Roma have shown in their famous comeback against Barcelona, you don’t need to give anything up as impossible,” a reporter from Rome told me this week.

Well, yes, but that was ‘only’ a 4-1 deficit as the Giallorossi came back to win 3-0 at the Stadio Olimpico six years ago to go through on the away goal.

They had the seemingly crucial boost of an early goal, Edin Dzeko scoring after six minutes.

De Rossi himself added the second from a penalty so may well quote that tie as a warning to his side at the Amex.

But a four-goal comeback? Look to Barcelona again, against Paris St Germain.

After a 4-0 defeat at the Parc des Princes, they came back to win 6-1 at the Camp Nou and pull off the near impossible.

They did so despite conceding the away goal which seemed to have killed the tie for a second time.

But they needed Lionel Messi, Luis Suarez and Neymar to help them produce the miracle.

Albion require a four-goal win just to force extra-time.

So maybe a 4-0, just like Liverpool managed at Anfield after losing 3-0 at Barcelona in the away leg.

Or 4-0 like Deportivo La Coruna enjoyed over Milan after losing 4-1 at the San Siro 20 years ago.

In terms of the Europa League, the best comeback was by Valencia against Basel but that was only after a 3-0 away defeat.

They wiped that out in 90 minutes and added two goals in extra time.

Going way back, Real Madrid had a reputation for European “remontadas” in the 1980s and perhaps the best saw them lose 5-1 at Bayern in the 1985-86 UEFA Cup, win the return 4-0 and go through on an away goal.

“Roma are big favourites, there’s no doubt,” my reporter counterpart continued in Italy.

“But with an early goal the atmosphere in the stadium will be incandescent.

“De Zerbi will prepare the match to get an early goal, in the first ten or 15 minutes.”

So will Albion’s fans buy into that? Will the atmosphere be incandescent?

Will the atmosphere be anything like that play-off second leg when the Seagulls aimed to wipe out a 2-0 deficit against Sheffield Wednesday?

That was a bit different. It was only two goals to pull back.

It was only Sheffield Wednesday.
But there was more to lose.

Why wouldn’t Albion and their fans give this a real go tomorrow?

Everything - almost everything - says they won’t go through, as indeed was the case that night against the Owls.

But, if they go out, it won’t be as heart-breaking as that play-off.

This is still only Albion’s fourth European game at home, the first in a knockout tie.

It is still an “I was there” occasion and it is still a live tie.

There can be excitement, memories and pride to be taken from the night.

If Roma complete the job, De Rossi needs to be looking as drained and relieved at full-time as Wednesday boss Carlos Carvalhal did almost eight years ago.

And there is another aspect to this game.

While the 4-0 scoreline was harsh, severe, Albion did not do themselves justice last week.

Their reputation as an emerging team took a blow at the Olimpico.

Italian press were scathing of Albion.

De Zerbi was told he lost the tactical battle.

We read in Italian print that Lewis Dunk made clamorous mistakes which cannot be committed at that level.

That Ansu Fati looked disorientated. That Igor erred badly in the same way as cost Fiorentina dear in last season’s Conference League final.

That Pascal Gross was slow and was beaten to second balls.

That Facundo Buonanotte should have said “good night” before he stepped on the pitch.

That Albion fans, after some initial noise, were silenced as they watched the “debacle” of their team.

And all that was in a few pages of the Corriere dello Sport newspaper.

La Gazzetta dello Sport were more complimentary about Gross, at least, but hammered most others and said De Zerbi was given a football lesson, adding: “The real genius is De Rossi.”

There is an awful lot of pride to be regained in some respects - and in the right way.

And a lot to be taken forward even if this is the end of their maiden European voyage.

So is it “rimonta” time? Any chance?

The dream would flicker a little more brightly if Albion had Joao Pedro and Kaoru Mitoma, their two most unpredictable attacking players.

Still, Simon Adingra is there. The Italians were impressed by him last week and he, if anyone, knows the ‘impossible’ can happen after his AFCON experiences.

The expectation will be for Seagulls fans to pack the Amex and to make themselves heard.

And for De Zerbi to send his men out looking to alter some of the impressions they gave at the Olimpico - and then to take it from there.

Roma will expect Albion to still believe.

And they probably don’t even know what happened between Sheffield Wednesday and Peterborough last season.

If might be “Ciao Europa” this week but it should not just fizzle out.

This adventure deserves better than that.
