Salah has announced himself as a world-class player during his first season at Anfield scoring 43 goals in all competitions, and picking up PFA Player of the Year award along the way. "Conceding two goals is not what we want but we can't change it, that's football", Klopp said.
"We really weren't good for 50 minutes and we lost all the challenges and duels and couldn't even make simple five yard passes", said the Italian whose team had been 5-0 down.
Liverpool, who won the match 5-2, said they were "shocked and appalled" by the incident.
"We believe the victim was in Liverpool with his brother for the Liverpool vs. Roma semifinal and was assaulted during an altercation between Roma and Liverpool fans near to the Albert pub at about 7:35 p.m. (1835 UTC)", police said.More news: Mourinho: Alexis Sanchez is going to be great for Man United
Fans group Spirit of Shankly have expressed concerns about supporters' safety for the second leg. We will fight with all we have.
Liverpool are now third in the league and in prime position to reach the Champions League final, after a 5-2 win in the first leg of their semi-final against Roma.
Liverpool are still not guaranteed the top-four finish that would secure a place in next season's Champions League and still need to travel to fifth-placed Chelsea, who could overtake them. "We made one mistake, the referee made one mistake [for the penalty], two goals for them, that's how it is". It will be a insane atmosphere but we played in one similar at Man City and we know what we need to do if we score quite early I think it will be a quite different.
"We didn't read the game as we should have done and we lacked quality". The Italian global criticised the hosts for not showing the courage to go toe-to-toe with them in the middle of the park, instead choosing to completely bypass the midfield and try to get Mane and Salah running the channels.
