No matter in any stadium, the cheers of the fans after the goal are actually used to express their inner joy. As for what they are shouting, it doesn't matter anymore, because they are already intoxicated with the joy of scoring at this moment.

Yes in the Premier League is actually very different from Yes in La Liga. This must be because of language differences. Usually Spain will send out the celebration sound of "ou", which is actually equivalent to the English Premier League's Yes.
