Yup, some of their top players will probably leave too. Utd should be all over Doucoure.
Troy Deeney was interviewed in Sky yesterday saying he had faith in Gracia to pull them out of the rough start and that he didn't think he'd get the sack, and now today this happens. I wouldn't be surprised if there ends up being a lot of discontent in the locker room over this, and chaos ensues and spirals.
If things really get unsettled, I could see some exoduses. More than just United should be all over Doucoure - I think he'd be an upgrade in the midfield for pretty much everyone except for City, Liverpool, and Chelsea. If United don't have the good sense to go for him, Everton would be a great fit. Deulofeu and Hughes would also be smart pickups for a lot of sides. There's a lot of talent in that squad - I think they would've recovered just fine if they had kept Gracia, but I'm not sure right now.
Timing is also weird, IMO. Their next five fixtures are really tough - Arsenal, City, Wolves, Sheffield, and Spurs. Seems like a bad time to give the sack and introduce some instability.
