The question here is, this so called arsenal is getting a striker really going to solve the problems? Because this arsenal that I am seeing is not really that serious in winning anything called trophy, how can you explain a team that have taken a lead with some reasonable points against their opponents, then at the end of it all lost it, and you're talking about striker, like it seems those guys are under the same spell that spurs just broke of recent, fine they might get a good striker but will the striker help them to win the league? Remember a tree can never make a forest, and even if they should get that striker if the spell isn't broken they will still not going to win anything that's my own opinion.
I don't think Arsenal are under any spell because I don't think there is anything spell in football. Those spell of a thing are just superstitious believe. In football when you do your business in the right why, you will get results and win trophies. Once a club are able to set their objectives right and follow it up with strategic signings, the right results will start coming in. From the Arsenal team it's obvious that they need a recognised striker. Their defence and midfield is working very well. To answer your question, yes getting a good striker will solve some of the problems in this Arsenal team that's just how I see it.
