There has to be a limit on a any human, where repeated losses when it really matters or counts would make one question themselves. Honestly ask yourself - how would you feel if you had lost like 8 finals having worked so hard to get to that position in the first place, and then get no reward.
I absolutely love Klopp and the way he managed the team. In the time we have not won the league - he stands out alone as one who does not hesitate to make changes to the team, and feels the pulse of the supporters like no other. He does not adhere to the GH and Rafa school of stubbornness - he adjusts and fixes those issues, and gets the right players in for his methods to work and at the same time playing football that we all enjoy. I so desperately want us to win the final - not just for the club but for him especially. There was an article in the Echo the other night about why this time might be different and his struggles int the last three cup finals and why we lost. But I have to say - I have serious issues with those reasons given, as I still think he could have done something different in each case - especially playing Lallana when Salah was taken off in last seasons CL final.
