It's a shame about Walcott. I thought he did really well when he came in, but he's definitely been struggling for large parts of this season, albeit I still think his presence has been at times enough to push defenders back. So even without getting assists he has been at least a little teeny tiny bit effective. I hoped he'd kick on from the goal he scored versus Spurs but that didn't materialize.
Not sure what's up with Lookman, you'd have to think something is not right behind closed doors there. That said, I don't think he's impressed as a starter either, definitely best used as a sub for the time being.
Bernard and Richarlison are our best wingers for right now, but I still hope Walcott can turn it around. I still like him in spite of this season's form.
