Just to see whether Bellingham is being unfairly picked on on this particular forum, had a look on one or two others.
This from Chelsea Shed End, for what it's worth:
Anyone else just don’t like Bellingham? Seems like an arrogant prick half the time. Just walked off the pitch at full time without congratulating a single Spanish player. Not even his Real Madrid colleagues. Seems like a sore loser when ever he isn’t winning and “big brothering” other players.
and
He's a complete c**t. Remember the CL games against Dortmund under Potter? We were winning so the c**t went, studs up, into Reece James. Dirty, cheating arrogant little twerp. Plus when he scored at the Euros giving it the "who else?". What a pratt.
Incidentally, vast majority of posters have pretty much the same verdict on Southgate. Obviously, they're very critical of him for not picking Palmer (something I'd be inclined to agree on, honestly) and favouring Kane, but pretty harsh on Phil. Not that Phil had a good tournament, but nobody much apart from us noticed how he was making runs and not being passed to. Bellingham, for me, certainly doesn't get a pass over Phil in the overall quality of his tournament.
