I said in another thread, that I'd put him in for the Final. Karius is no better - he has benefitted from the defence getting their act together, that's all. Mignolet would have done just as well in the last few months.
Not sure where to check the stats, but there can't be an EPL keeper around today that has saved more penalties than Mignolet. And a shootout is quite likely - I think there have been 12 or 13 finals that have gone to penalties.
Would that decision annoy Karius? Yes - but so what? Every decision Klopp makes must be taken to benefit the 'club'.
I agree we do what is best for the team.
What we can say is that since Karius, VvD & Robertson have played together we have improved allot in defence, that could have happened with Migs in goal, but we don't know that.
The current defence has played together for 5 months, so they are used to each other, VvD has never played with Migs as far as I know, Robbo has hardly played with Migs, so changing GK now would be a massive risk and a mistake IMO.
It's not as if Migs is some returning superstar keeper worth the risk, they are pretty similar IMO, but Karius has more potential as he is young, but neither is long term good enough if we want to win the PL. I think having Migs on the bench for a penalty shoot out is worth a go, he's on the bench anyways, would be a massive call on the night.
