Of course they can be discussed but its about context. Using phrases like 'poor' team management when your team has completely obliterated and nullified the other team from having the ball and barely having a shot on goal and making the right subs who in the end win the game for you, sounds out of context.
Just on Leckie, he is a bloody Bundesliga player lol. Plays for the national team. He is still getting match fit, and we're only 4 games in, with 2 wins and 1 draw. I believe he has earned the right to have time to find his best performances.
