This has been addressed in post match comments, Roony needed to come off - not sure Lamine was planned for many minutes, if at all
Could be recovering from illness unrelated to the knock but until Flick is asked about it, no way to be certain
I will say that team selection for 1st Newcastle encounter and by extension Sevilla had the look of very calculated & strategic choices with Wednesday's return in mind. I do think there is an aspect where he is trying to ensure he has depth in key areas to trigger at Camp Nou - while the attack is one aspect, Frenkie's absence is the most concerning tactical issue Hansi has to account for. Will it be Bernal paired with Pedri in a double pivot and Raphinha dropping in as a link to the front 3 of Marcus, Ferran & Lamine...or will it be Olmo/Fermin in the hole
I suspect a tactical tweak for Wednesday as we have yet to see the best version of Barça IMHO
