Hull were dead and gone. I think it would be silly to pin that on him, and I'm sure you realise that. It was amazing they still had a chance going into the last few games. And the change in their team was marked.
It's not a question of whether someone is foreign or not, as you weirdly appear to be fixating on that. It's about whether they can do the job or not, and then whether they would have the potential to move us on from 7th (assuming we get back to that area of the time in the near future).
That’s not true. When Silva took over Hull were 18th on 16 points with 17 games to play for, behind Palace on goal difference and just a few points behind Boro and Leicester. It was hardly an insurmountable position. They ended up 6 points from safety despite a free falling Watford and Burnley. Swansea looked dead and buried when they appointed Paul Clement a week earlier but they gained 8 more points on Hull during the remaining games and finished relatively safely.
Silva’s got two big negatives, one being he’s very flighty and the other is his teams concede on average a goal a game (two a game in English football), fortunately he seems to enjoy attacking though and his teams score a lot. His appointment would make for an interesting and unpredictable ride by the looks, he’d be a big gamble and it’s probably why Moshiri is taking so long to consider it.
