Klaus disagree with this assessment on his use last season.
The reason Rodrygo didn't have more league games last season is because he wasn't in the squad towards the end of the season because he fell out with the club but he was regular in the first team prior to that even if they weren't building the team around him. You just have to see that he started 10 out 13 CL games to confirm that he's a regular in the first 11 in games that matter.
The fact that he's not playing in CWC is unusual - it's either the club now forcing him out or protecting him from injury in case there's a sale to be had or the player continuing the disagreement's he had towards the end of last season. He's definitely been singled out during this tournament. None of this, of course, means that he's interested in joining us - I suspect we're not at the top of his list even if he did move.
Also I don't get your point about him moving positions. 63% of his time was off the RW - that's partially the issue Rodrygo has. He wants to be either CF or LW which will never happen
