I think you're the only one I've seen who says Romero had a good season with Genoa. Not many regretted us not bringing him back.
Anyway, I'll leave it there.
He played 30 matches (in only 1 season he had 9 games more than Demiral in two seasons) in the last season he was at Genoa, scoring 1 goal and giving 2 assist
He played 27 games the season before hat scoring 2 goals and 1 assist...
that´s 57 Serie A games for a 18-19 year old defender...
So... yes... I think he had a good decent season with Genoa... as a matter of fact he had 2 good decent seasons...
Yes, you can argue that "it was for Genoa" but he was showing what we are seen now, that he was, is and will be a top player.
