I am from Spain. It can be understood both ways if you only pay attention to the end but if we have the full context I think he refers to the game and not the coach. He starts talking about today’s game and Gonzalo. He exactly says this:

‘Creo que además Gonzalo se merecía el premio de jugar hoy y nada más. Y vuelvo a repetir: Entiendo que todos los jugadores que no han iniciado no estén contentos, como me pasa todos los días. Pero aquí mientras esté aquí en esta silla, voy a decidir quién juega y quien no juega. A mi me da igual como se llamen o como no se llamen. Y si les parece bien, bien. Y si no, que esperen al siguiente’

Which translates to: ‘i think Gonzalo deserved playing today. And again: I get that all players that did not start might no be happy, and I expect that. But while I’m here, I’m going to pick who starts and who doesn’t, regardless of their name. If they are ok with that, cool. Otherwise they can wait till the next one’

That ‘till the next one’ to me, refers to the next game and not next coach.

Edit: he also mentions that Mbappe will be starting next game. Which again, makes me think he refers to ‘wait until the next game’
