And it's MUCH clearer in football not to mention there are MANY more of them. So an actual clock is more important. A quarter in football can last an hour -- a half in futbol is usually an extra few minutes max. But it would likely triple if not more by adding a layer of personnel and the resulting communication and miscommunication. How often do you hear "please reset the game clock ..."? That's fine when you have built in stoppages already and when it adds a proportionally low amount of time. That's not the case with soccer.
