Jurgen Klopp’s men go into the second leg leading 5-2 from last week’s impressive performance at Anfield, but Ferdinand has warned any complacency in Rome will come back to bite them.
“They’re going to have make sure that mentally they’re ready – it’s going to be a huge, huge, crazy atmosphere with the support the Roma fans create for their team,” said the former England defender.
“It’s at the Stadio Olimpico and there’s a lot of history there, so they’ve got to weather that storm, and there’s going to be that 10-15 minute spell where Roma come out and give everything.
“That’s what happens in these games. Liverpool are going to have to be mature enough and composed enough to get through that bit of craziness which is going to come into the game. That is normal, these games create that type of atmosphere.
“Anything is possible in football when you’re out there playing. If there’s any complacency, you will get punished at the top level and Roma have proved that already.
“But Liverpool have enough good players to silence that crowd and that’s what they’ve got to think of. They have to ride that storm but we know that at any given moment in that storm that Liverpool have players who can hurt Roma.
"They need to be ready when the chances do come, to put them away. We saw Barcelona have chances to kill the tie off but didn’t capitalise and didn’t finish them off and got punished.”
Mohamed Salah has been the standout player in the Premier League this season and has also delivered in the Champions League.
The Egyptian ace tore his former side apart at Anfield last week and will now return to Rome for the first time since leaving last summer.
And Ferdinand doesn’t believe Salah will feel any pressure against his old employers on the back of their 5-2 lead from the first leg.
“It can be mentally draining and you do think about it, but I think because Liverpool go there with such a good cushion probably takes the pressure off Salah a bit,” he said.
“He can probably go there and relax a little bit more than he would normally, so I think he’ll be in a good place.”
