In my opinion I don’t think just signing a striker for Arsenal settles the problem for not winning trophies. Arsenal lack that winning mentality and strategy to push cross the line when they need to. For three seasons now they have always come close but failed to push through at the very last point. If signing a striker will help Arsenal get it right then thank heavens but I still feel it is not enough.
Yes, it is not yet completely solved. They need to develop the ability to play under pressure and avoid making mistakes at the end. In previous seasons they had problems with their strikers which they have solved this season. But that does not mean they have won the title. The attacking mentality to win the title and the ability to plan and perform well in the final matches is not yet fully present in the Arsenal team. They need to work on this more.
