Pogue Mahone
Closet Gooner.
He has played ~800 minutes for us so far. From those, in only the last 180 minutes against Barca and Leicester did he play a portion of the game as an Attacking Mid or Support Striker. And even then not whole game. You're making it sound like he has played 3/4s of his time as a DM or something. That's a pretty poor defence of his (lack of) effectiveness in front of goal.
I’m not trying to argue he’s a productive striker. He clearly isn’t, so far. But he’s only a few good saves/the width of a post from being acceptably productive, considering the role he’s been asked to play in the team and the sort of player he is. He’s obviously been signed as someone who can get the best out of those around him, rather than score a load of goals for us. Look at the way he created space for Sancho’s goal. That’s the sort of movement so often lacking from Martial’s game.
