Is it really though?
We have a bunch of players that have been performing poorly with their most realistic chances of getting first team football being taking big steps down in terms of club stature and salary.
If you're Dier, Reguilon, Sanchez, Ndombele etc, taking a move to a Fulham, Galatasaray, Genoa or whoever comes in will pretty much end your career at the top level. Professionals ought to believe in their own ability and ought to hold out for what they think is best for them - but no half decent clubs in Europe will want them... but you never know who Atletico Madrid might throw a lifeline to I guess.
As we all know, clubs will speak with players or their representatives about potential moves before even tabling an offer. I know it's trendy and easy (if not lazy) to just blame Levy - but I'm blaming the players for being so fucking shite that no clubs they would want to join are getting in contact with them.
Then I blame their agents for not being the salesmen they require.
If Levy is sitting there rejecting bid after bid for these players that have already agreed in principal to join other clubs that's a different story, but I really don't think that's the case.
