Arsenal needs a striker urgently, Gabriel Jesus is not reliable enough and cannot guarantee Arteta the goals needed every season to compete for silverware. This season and even the previous seasons, we saw on different occasions where Arsenal played well and just needed the goals to get a win but failed to accomplish that. A striker like Osimhen can guarantee more goals, you can agree that goals win you games no matter how tough the opponent is.
If he urgently needs it and has the money, he can buy him wherever and whenever he wants, the problem arises if he needs a good, young striker who wants to pay little.
He never finds that.
When I hear these urgent things I am always reminded that you can easily find everything if you are willing to pay.
