Watching the world cup (and previously the champions league), Olise has simply gone to another level since he left Palace, he is without doubt world class.
Watching the France games, you could say he is the player that makes France tick at the moment. His assists and contributions are significant.
Shame that scissor kick have went in against Sweden, that would have been some goal.
Not saying that without him France would struggle as they have far too many other exceptional players as well, ie. Barcola coming in looked awesome as well.
Before his senior competitive international debut, he could have played for 4 countries, France, Algeria, Nigeria and England (the country of his birth).
To my knowledge (and I stand behind corrected here), England made no attempt to really try and persuade him to play for England (remember, Southgate was manager back then).
Now ask yourself, who would England rather have at this WC cup, Olise or Saka ? (With the exception of deluded Arsenal fans, who still think Saka is truly world class).
I know that Olise only played for France youth teams, so that probably indicates his intentions, but it seems England didn't even bother trying to persuade him.
One of the few players that makes you watch games at present.
