The coach refused to dwell on the exit, instead highlighting the progress made by his squad on the international stage.
He also addressed the decision to leave Alphonso Davies on the bench, revealing tactical and fitness considerations behind the move for the crucial knockout tie.
While the result looked heavy on paper, he argued the performance told a different story against a disciplined Moroccan side that has impressed throughout the tournament.
“Man, we were the better team. We were the better team. Right? They made a couple more plays than us, but cranking up the intensity was not the issue,” Marsch told TSN.
“It was just that they had a little bit of quality in the final third, and we lacked a little ability to make a play when we needed to.
“But in terms of the match plan, the idea of how we want to play football, the idea of a bunch of guys believing in themselves and going after it, and taking a top team who haven't lost in – I don't even know how long – and taking them to the limit, we were the much better team in the first half, and even at the beginning of the second half. It was one play that made it 1-0; otherwise, the game was ours.”
