Filippo Monteforte, / AFP | Liverpool defeated AS Roma 5-2 at Anfield in the first leg of their Champions League semi-final tie on Tuesday April 24, 2018.

Mohamed Salah came back to haunt former club Roma in spectacular style with two goals and two assists as Liverpool stormed towards the Champions League final with a 5-2 semi-final, first-leg win at Anfield on Tuesday.

Roberto Firmino also scored twice and Sadio Mane netted Liverpool's other goal to make up for missing a series of gilt-edged chances as the scoreline did anything but flatter the hosts.

Roma produced one of the finest comebacks in Champions League history by overturning a 4-1 first-leg deficit against Barcelona in the quarter-finals.

They will need to do the same in the return leg on May 2, but the visitors were at least given a lifeline when Edin Dzeko and Diego Perotti grabbed two vital away goals in the final 10 minutes.

"This reaction is welcome because we give meaning to the return match," said Roma coach Eusebio Di Francesco.

"We have to believe, in football everything can happen, it will be a different match from the one with Barcelona, but the desire to overturn it is there."

Liverpool will rue their missed chances and poor late defending, but remain well on course for a first final in 11 years.

"Of course we would have been more happy with 5-0 or 5-1 but 5-2 is a fantastic result. We go there and try again," said Liverpool manager Jurgen Klopp.

"We scored these goals and could have scored more. That is all positive, at this moment it doesn't feel all positive because they scored these two goals but tomorrow I will see the really good part of the game."

The hosts' early rhythm was disrupted when Alex-Oxlade Chamberlain was stretchered off with what Klopp described as "probably a really bad injury", putting his World Cup dreams with England in doubt.

Moments later, the visitors were inches away from the opener when Aleksandar Kolarov's long-range strike slipped through the grasp of Loris Karius and came back off the crossbar.

However, Liverpool soon settled and should have put the tie beyond doubt before half-time.

Mane blazed over when clean through on goal and then skewed wide when teed up by Firmino.

Unselfish superstar

Roma have now lost their last four Champions League away games -- shipping 13 goals in the process -- and were punished by the man they sold to Liverpool for what now seems a bargain 42 million euros (£37 million, $52 million) last year.

Nine minutes of the first half remained when Salah picked the ball up just inside the Roma area and was given far too much time by Juan Jesus to cut inside onto his favoured left foot and curl the ball with unerring accuracy into the top corner.

Brazilian number one Alisson has been in stunning form but even he was powerless as Salah struck again in first-half stoppage time with a trademark dinked finish over the advancing 'keeper.

Chasing a first ever Champions League hat-trick, Salah would have been forgiven for going for goal as he bore down on Alisson once more 11 minutes into the second period.

But he showed why he is considered one of the game's more unselfish superstars by squaring for a relieved Mane to convert from close range.

Salah wreaked more havoc five minutes later when he sped past the helpless Jesus and pulled the ball across goal for Firmino to tap home.

Firmino then rose highest to head in James Milner's corner to take Liverpool's fearsome front three's combined tally for the season to 88 goals.

Roma's night seemed to be summed up when midfielder Kevin Strootman and coach Di Francesco became engaged in a blazing row after the fifth goal went in.

However, Klopp's decision to withdraw Salah 15 minutes from time backfired as the tie swung back Roma's way in the final stages.

Firstly, with nine minutes left, Dzeko slotted home his 21st goal of the season as Lovren got caught underneath the ball.

Moments later, Anfield was stunned when Milner was punished for handball inside the area and Perotti coolly slotted home the resulting penalty.
