Other than Wales, I thought set piece delivery was good throughout. Other than McKennie, we just don't have guys that attack the ball in the offensive box in the air.
The team we need to emulate offensively is Argentina.
Ever notice that there is no such thing as a hopeful cross into the box from them. Balls from out wide into the box are either early balls, usually on a counter or from a guy getting to the touchline, many times close, or inside, the box. Their goal is to probe and to probe and to create a mismatch somewhere to get Messi the ball at the top of box.
We obviously don't have a Messi but scoring off of long, high balls from wide into the box is, currently, something we are not good at.
Of course, this is much easier said than done. You need all your attacking players, including your fullbacks to all have close control and be able to play those quick little one-twos. We are almost there, just need to get better at it and also have better defined ways of creating those mismatches. We do do it, but not consistently.
