I have no idea why Unai started him today. Like all our midfield he struggled with the basics, completing a simple pass was beyond them. Onana was slowing down the game to pedestrian levels when we desperately needed a forward ball.
Whatever Unai was thinking about having Onana playing alongside Kamara with Youri further forward, I really hope he doesn't do it again. It did nobody any favours other than Newcastle. A real tactical brainfart.
