I absolutely adore Brahim, but I don't think his finishing in the 6 yard box is up to the level of the rest of his game. The last few weeks I have seen him playing false 9 he's had so many chances where he should score, especially at the front post. And they aren't all really bad misses - they're just the kind of chances you'd expect a really talented forward to finish. If he could add that edge to his game he'd be unstoppable because he's running Ilori (23) and Mamadou Sakho ragged.
Plenty of time to polish it though, and I know false 9 isn't really his position - perhaps he's just not as familiar with the sort of front post
I think Tosin's passing has improved this season - it's more purposeful, it feels like he's moving the ball for a reason, not just because that's how we play.
