Sicario2 This is prob the highest profile game he would have played outside a ‘title race’. Def most high profile European game. This is where players reputations are made, not by scoring a brace v Burnley.
If you want to be WC you must show up in these games.
Ok, so he shows up in this game and he's WC if he doesn't then he's not. Let's assume that premise holds.
After that, if we go through the first leg of the next round is then the biggest game he'll have played in, in which case he will have to prove once again whether he's WC or not.
Each subsequent CL game will be the same, where he can only prove he's WC until the next game where he'll then have to prove it again and again. Until he actually wins it and cements his WC status permanently, or he gets knocked out.
Look, Saka may or may not be WC, but he's a damn great player and one of the best in Europe. One game here or there doesn't decide that outside of those silly WPOTY awards and the like. The people who claim this are the same ones that used to argue that Thierry isn't WC because he never scored in a Final like everything he did before that point counted for nothing.
