A few observations:
1. Walcott is a RW, not a ST
2. Elneny continues to impress, we're a lot more fluid with him in there
3. Our back up fullbacks are atrocious
4. Hate to see an injury to any player but the silver lining with Gabriel going down is it forces Wenger to bring someone in and sadly, Gabriel is/was a mistake waiting to happen back there every game
5. Iwobi needs to be starting more games
6. We badly need a clinical striker up top
On point.
