This.
And hope he'll do well enough fans won't boo him if he'll play at Camp Nou again. I understand why fans would boo him but people should also be aware this could negatively affect a whole team. Yeah, he made a business decision for his career we're not happy with but most of his team mates surely understand that and are still close to him. This team needs as much support as they can get to get through this difficult period not fans turning against our own player.
I'm sure Xavi is well aware of that and will protect the team so it's very likely Dembouz won't play home games unless we'll suffer more injuries upfront. I'd still prefer to use him over Abde or LDJ for example.
The problem is that most of the fans (people inside the club probably as well) think that he is an ungrateful piece of shit.
Barca paid an enormous amount of money for him and to him in the years that he was here. Fans loved him from the start and supported throughout all the injuries. His contribution to the team in all his time here was basically non-existent and now when he can help the club, he wants to be paid like Neymar or whatever and is leaving for free.
I understand his business decision, he wants a big contract to financially ensure himself for life, but as a fan of Barca I will think of him as an ungrateful cocksucker and that`s it.
That is why it is very difficult not to boo him, but I agree it`s detrimental for the team as well.
