I am sure that nothing will change if they have one additional player who can score. It's not just about one player, but about the team itself and their tactics. What's the point of having a goal scorer if they can't pass the ball well to him so that he has minimal problems on his way to the goal? That's why they need more in-depth work than just a player at the forefront, which they already have.
Change ought to be constant in a team because it varies every season and also the players. The formidable ones coming to peak and also losing form and stands. Who doesn't love football? It's epic and world-class, there's actually more we've watch and enjoyed in this football space. A goal is always seen as the most important feature of most players specifically pointing to the direction of the attackers. Of what use are they if they don't have the capability to enchance their foot and bang goals? More like a woman that can't give birth to a baby, a barren lady, exactly the scenario applied to attacker.
