Erling is 100% a blue. There's enough out there of him in City kits over the years to suggest it's more than a 'kid supports his dad's team' phase. He literally supported us in the Pearce era FFS. I even heard a story that apparently he had to leave all the City FB groups once he turned pro.
Although, I do think he takes his career seriously enough to not let that be a deciding factor. Not unless he's unsure between two teams, it might become a tiebreaker then.
On another note, it's endearing that Alf stayed on as a City fan. It's possible he's following his other teams too, but he wasn't exactly at City for an extremely long time, so the fact he has a soft spot for us means he must have had a great time, despite everything that happened. Maybe he was overwhelmed by the support during his recovery?
