Karius I think just got caught cheating to the wrong side. A freekick from 25 yards, he should be central, because any decent player taking the kick will be able to put it over the wall.
Just another sign of inexperience. He needs more games, but hopefully he won't make any more mistakes that will cost us CL points.
Can, on the other hand, I just hate watching players who are just a bit light up top. It's so frustrating at times, more so than watching a good player struggle. Hard to cure stupidity.
