But I must really admit that it was a superb match! Both sides made a huge effort and that comeback by Manchester United in extra time was really worth watching. Amad Diallo can't find much chance to play but this youngster scored the goal to bring the semi finals to his team in the last moments. 
Klopp must be sad after the result but he still has the Premier League and Europa League titles waiting to be achieved too.
They played well and indeed even though Liverpool lost but they also fought very hard in this match even though the results were not as expected. Klopp must be sad after the result but he still has the Premier League and Europa League titles waiting to be achieved too.In this match Liverpool played very well but Manchester United were able to provide good resistance because they also seemed to get new strength when playing at their own home because the supporters who provided support was really a separate pressure for Liverpool in performance .In addition Liverpool fatigue factor, which is indeed too much in terms of players and young players who are still not too mature also in terms of decision making, is one of the situations that does need to be considered but it is also good for the development of some young players.
Now Liverpool only have to refocus on the EPL and Europa League currently their chances are still very large in this competition, do not let the defeat in this week's match in the FA Cup disrupt their momentum in other competitions.
