I don't think that's likely to happen especially now Girona are on fire hard to beat if their coach leaves then it will be chaotic.
This is just a rumor, it is not clear what will happen later whether Eddie Howe will be replaced in the near future or kept by Newcastle.
It's just a rumour I think. They might be having some thoughts but I don't think think it will materialize in the end. Girona are on a great form surprisingly this season and I don't think that Girona at all are willing to let him go in mid season as they will lose the momentum if anything changes inside the squad. Besides Newcastle will be discussing inside about sacking Eddie Howe and getting a new manager but to sign Girona manager Sanchez seems very hard to me.
I mean Eddie Howe is doing an alright job. But I guess it was not enough for the Saudi Owners. But we have to take a look at where he is being held back. He has a big list of injuries. Probably his team has suffered the most injuries in the Premier League. They have not spent much money either considering they are a team owned by the Arabs. But I think they should not sack Eddie Howe. He got them the ticket to UCL last season and if the team stays out of injury then they can achieve it this season as well. The Premier League is very competitive so it is no easy job.
I don't know if Girona's coach will be enough either.
