When the team does well, we give accolades to Klopp, but when it is the opposite, we start saying it is his fault. In that game, i would say the team were reluctant in the field, that is why the second goal from Manchester United came in. Klopp gave a good strategy of play to his boys; they tried it, and it worked in the second half.
Let us be sincere here, Klopp has done his best for this team. I know it is very painful that he lost in the game because, since he is going to leave Liverpool soon, he needs to win a trophy as a courtesy. Now the EPL league trophy is slowly slipping out of his hands. Manchester City and Arsenal are on it again.
And I'm not disputing that. Earlier I said in some games you lose some and win some and you can agree with me that Liverpool are another team who have been consistent in keeping good records, winning games both home and away and are a force but that doesn't mean they won't make mistakes or Jurgen Klopp isn't a mortal. For a team who is plagued with player injuries, it's a wise decision he took by withdrawing his key players so they can be able to fight a bigger battle in front of them. Man UTD have won the quarter finals and have moved on to the semi's but there's no telling if they can be able to get past that round so if Liverpool couldn't do the job, I guess someone else may do the job.
I think Liverpool are more concerned at the moment with winning the premier league if possible or excelling in the Europa league so I doubt that being knocked out of the FA Cup competition is a big deal for Klopp because if we look at it, the Premier league title or Europa league title holds more prestige than the FA CUP TROPHY.
