Bizarrely, the stringent ways MA has run us in the past, will allow us to spend heavily if and when that's what they want to do. It's actually odd to think that we could potentially need to be grateful to MAEven if they aren't in the relegation zone they'd have to pay a premium. Newcastle aren't an elite club, they can't offer champions league football (even if they get Europa eventually it'll do little as its such a devalued competition), so he'd need a massive wedge (and then you wonder how committed he'd be).
This takeover definitely gives them hope from a footballing perspective. There's a chance that IF the Saudis really want to have a top team they could bankroll them. Issue is they're going to be closely watched around FFP, especially with every other club in the league against them coming in. They'll need to do what City did and build slowly. That's probably not easy to do though, especially with the extra restrictions in place nowadays. If they don't get the right people to oversee recruitment etc they could struggle. Again, a few years of wasted money won't hit the Saudi bottom line, but it'll make FFP even harder to adhere to. The ones thinking they'll be winning the league in 5 years are likely being massively optimistic
