You guys are so odd, like you are watching a highlight but are so determined to criticise you don't actually watch it?
Criticise him for real things - his touch, losing duels etc. he wasn't particularly good vs Arsenal but he did well here. His job in this scenario is to either make a run so that he can receive the ball in a position to shoot or make space for Garnacho/Bruno. Why do you think he wants to go behind the far CB? Like, come on, this isn't even about playing football it's just using your noggin. He either bursts to come near post and Garnacho has the option to slip him in near post, or he does what he does. Staying central helps no one, he's just in the way. He has to get the covering defender more towards the back stick and Bruno will obviously come inside for his right foot.
The more you watch the clip, the more his movement looks good to be honest. The initial reaction to Garnacho winning the ball is what every striker should do, he drives behind the nearest CB and forces him to cede all the space to Garnacho. Then he picks a post and commits to it. Explain what he's done wrong here?
