Merino, Havertz and Jesus all move around the pitch, come short, go wide, drop deep, move all over the fucking pitch to get involved, get touches of the ball and generate shots and chances for themselves. Gyokeres stays stuck on the last line for pretty much the entire match, that is his playing style, but that's why I never got why people were so obsessed with a box striker - they offer so little.
Gyokeres needs to change how he plays but I suspect it's too late in his career for that.
