On yet another historic European night at Anfield, Liverpool destroyed Roma 5-2 on Tuesday to all but guarantee their place in the Champions League final.
Goals from Mohamed Salah (2), Roberto Firmino (2) and Sadio Mane secured an emphatic victory that should be enough heading into the second leg next week.
It would take a spectacular collapse from Jurgen Klopp's men for Roma to produce a comeback, though the Italian side proved against Barcelona that they should never be underestimated.
However, the game was shrouded in controversy as Roma ultras used weapons to attack Liverpool fans outside the stadium in the build-up.
Nine men have been arrested for various offences, with two Roma fans currently being held on suspicion of attempted murder after hospitalising a Liverpool fan.
According to various media outlets, the Liverpool fan is in critical condition and fighting for his life after being hit over the head with a belt at 7.35pm outside the Albert pub.
A statement read: "Liverpool Football Club is shocked and appalled after a Liverpool supporter was left in a critical condition having been attacked prior to the Champions League fixture against AS Roma.
VIOLENCE OUTSIDE OF ANFIELD
"Our thoughts, in the first instance, are with the victim and his family at this very traumatic time. We will be offering them our full support.
"The club has been liaising with the emergency services since the incident occurred and will continue to do so."
Shocking footage, which you can see below, shows Roma ultras using belts as offensive weapons as a man lays on the floor motionless. One fan was even caught wielding a hammer.
Tony Bellew has now condemned the attack on Twitter and he wants the two Roma fans to be made an example of.
Liverpool fans were widely slammed for throwing bottles at Manchester City's team bus a few weeks ago, but this is a whole new and disgusting level that just isn't acceptable.
It's since been confirmed that no one was stabbed and the Liverpool fan is Irish, but violence has no place in football and fans shouldn't be made to fear for their lives going to games.
Our thoughts are with the Liverpool fan and his family at this time. Hopefully he makes a full recovery.
