Akanji said afterwards (via The Guardian): "When we got through, sometimes they stopped us with the fouls. If there's no action [from the referee], it's hard. I don't understand. One in the first half [from Kai Havertz] was a very late tackle on Stefan [Ortega]. For me, it is clearly a yellow card. I don't want to say just against us. There were also some decisions against them that I didn’t understand why he gave a foul.
"There are some rules and I think there are clear yellow cards where it should be. I remember with Jorginho when he'd already done a tackle [which was a foul] and did the second one and he didn't even give a yellow card for one [foul]. I didn't understand some of the decisions but, in the end, we still should be able to score a goal."
