Ah so here’s the narrative emerging. Doku should have had a yellow for ‘kicking the ball away’ in the first half. Never mind that he was actually kicking it back to where the free kick was awarded.
We need to be patient here. Keep possession, and play our passing game. With the man advantage, you'd hope that an opening would happen. We have to capitalise if/when it does; chances will be few and far between.
