The final match will be a difficult match for both teams and I hope we will see both teams will put all their abilities into making the match really fierce, I personally am not a Liverpool fan, but hope that Liverpool can end this season with a trophy champions league after their failure to win the English league, Salah who is the spearhead of Liverpool attack so far is still in doubt will appear after the injury he got in the last game, it will be a big loss if Salah misses the match, but I think if later Salah is absent, of course, Klopp still has the right solution in destroying the madrid defense.
Without Salah I think Liverpool will be difficult to win a game against Real Madrid. Indeed, several other players can still be used to fill the void in Liverpool's attack, but it is completely different when compared to Salah. The situation may be difficult if Liverpool have to lose their two main pillars in the final match, but there is still a possibility they can be played.
I think Salah have back from injury after last match play when Liverpool against with Wolves and success made one goals, I think he will back on the final match against with Real Madrid. But all Liverpool player still memorize failed on primer league league how they can't be the winner in this season and last matchday although success defeated Wolves but other match Manchester City success defeated Aston Villa, maybe right now focus on champion league and never try get second time failure and loss chance with champion league final match.
