I care if we concede the way we do. A proper GK would most likely save those shots or at least be closer to saving them. 5-2 win is OK if opponents score good goals.Who cares how much we concede if we win at the end lol. Flick conceded 2 against Setien's Barca too. Sounds crazy but not so much when you realise he also banged 8.
Madrid reached CL final with Lunin against likes of City, so evidently they could win big games with him in goal. But in the final it was still the best who started, Courtois.
Should be the same for us. We have beaten Bayern and Madrid with Iñaki but we have this GK who is a better player than him on the bench that we for some reason aren't playing.
We have no security once they get past our defense. Iñaki is a highly average GK who managed to have a Kameni esque once-per-season superb game against Madrid.
