sorry for saying this for about the 100th time but this is more down to some players never facing the consequences of playing terribly
Gylfi has been terrible for almost his entire time with us, but he's captain here - in any walk of life you can't tolerate bad performance like this from a couple of people because it wrecks the harmony of any team. He should be kept out until he earns his place back.
that’s because they’re never without them. When was the last time they started a match without their five best players?
