I agree, they need to be more effectual in goal-scoring.
The 2 wingers need to become more unpredictable to defenders in their positioning, coming wide or inside. Kent does this better but he is not effectual enough when he gets into goal scoring positions. Too often crosses are too long or too floaty, but because the opposite winger is sitting too wide (leaving usually only 1 attacker in a goal-scoring position) it is being picked up by the winger. If we are going to have fast wingback style defenders, they should be picking up that over-hit cross with the opposite winger becoming the 2nd attacker in front of goal.
Also, draw a semi-circle from the goal about 15 yards out and in that area we are too often chaotic. Crosses are not reaching attackers, incisive on the deck passes are not reaching anyone except defenders and there are not enough attackers in that area. Instead, defences are packing the area and booting the ball clear. If teams fear us having the ball in that area then they will sit further from the goal to try to prevent the ball getting that close to the goal, which will lead to more space once we get there. For this we need better players or our existing players to improve how often they get in such positions and what they do when they get there. There's too many players at the moment waiting for the ball to pop back out to them, which of course it does because there is no one there to make something happen. Too often we're playing tennis with our advanced midfield outside the semi-circle and defenders inside it. We need to be more ruthless and go and get goals rather than hope Alfie will get lucky.
There are many other factors and situations but these are 2 clear situations that happen regularly in matches that have potential for goals but are mismanaged by the players in very predictable ways.
