Jose came in, established that Eriksen didn't want to be here, and left him out. The CM crisis is so bad that he's had to go back to him with his tail between his legs. Put yourself in the shoes of some of the others. This guy is getting picked and doesn't even want to be here. it's going to unsettle a few I think.
I think this is overstated a tad by fans because of our own emotional connections to the club.
We feel spurned as fans because Eriksen has made it clear that he wants to leave our beloved club.
Other than Kane and Winks, nobody else in the squad has an even slightly similar connection. They all want to win, that is their primary objective. And actually that includes Kane and Winks too.
So I doubt they're looking back, thinking we've got a bit of a crisis at CM but I hate Eriksen now so I don't want him to play. They'll want whoever can maximise our chances to play.
Unless someone is being actively disrespectful or being an ass, I can't recall any players mentioning how annoyed they were that someone who was leaving was being picked, especially if there aren't other alternatives.
If Winks, Sissoko, N'Dombele, GLC, Skipp, Dier were pulling up trees or dominating and still being dropped for an ineffective Eriksen, they'd have reason to be unsettled. As it is, they're currently a mixture of injured/ poor/ unreliable/ not yet up to scratch/ pussies/ young/ suspended.
If they start putting in better perfmances, he'd be phased out, as both Poch and Mourinho have tried this season, only to have to turn back to him because of the above. And because he's still one fo the few players in the squad who is a game winner, even with his drop in form.
