Most of all, though, there's just a sense of sadness that such a beautiful Liverpool love story is going to have such an unhappy ending. One-club men are few and far between these days, but Alexander-Arnold looked like he was going to be one of them, the Reds role model that blazed a trail all the way from the academy to Anfield.
He once claimed that the trophies won under Klopp were of greater value than those claimed by Manchester City during the same timespan because "We're up against a machine that's built to win." And yet now he's joining state-supported Madrid, the richest and most successful club in the Champions League.
The move makes no sense in that regard. But then, as Alexander-Arnold said himself, he's no longer driven by winning trophies with a particular team. This is purely about achieving personal goals now. There's nothing strange or unusual about that, of course. The majority of modern footballers think the exact same way.
The supporters are still going to be upset, though. The best that Alexander-Arnold can now hope for is a respectful farewell during the final weeks of the season given he has been negotiating a transfer to Madrid while Liverpool were fighting for the title, thus creating a wholly unnecessary distraction.
The Reds' deep-rooted resentment is also understandable. Trent was one of their own, the local lad living the dream, a shared dream. Alexander-Arnold realised his, though, and now he's got himself a new one.
In his eyes, pursuing the Ballon d'Or in Madrid means more than wearing the captain's armband at Liverpool. Unfortunately, he'll never get his hands on either - and only Alexander-Arnold will know when he looks in the mirror after retiring if it was a sacrifice worth making.
