None of them try, none of them care. Simple as that. Mercenaries all of them.
In an ideal world you'd sell them but who would buy them? If I was a manager these are the kind of players I'd steer well clear of. They'd toxify any team spirit you would have.
I'd fine them but with agents these days the players have more power than they should and therein lays one of the big problems.
You know that this relatively same team will be back for the next match. They're safe and arrogant in that knowledge. That's why they don't make the effort. Why would you if you can get away with it? Pride, true, but none of these have any therefore it's not a problem.
Don't be blaming all the managers, its the players, full stop.
The next time one of these kisses the badge just think back. Enough is enough. They've survived too long on the back of scapegoating the managers (some were crap true) but you get my point.
They've failed us that many times already this season already that the recent 'good' performances just didn't ring true.
