One thing to note is that the owner of Mancity's worth is $34bn and the owner of Newcastle's worth is $320bn! Almost 10 times that of Mancity's. So if Pep can spend around $200million on each window, they can easily spend $500 or maybe $1bn each window.
That is quite huge and any manager with such funds at their disposal can built a dream team from scratch. Few decades ago Newcastle was more informed that Manchester city then the oil money came and turned things around. Newcastle has been bought now and I can see same thing happening again. Already the mindset of the club owner is to win. Just like Leicester City winning the premier league from no where I would not be surprised if Newcastle also win in next few years.
The main priority now has to be not getting relegated. Can Newcastle buy new players in January? If they can, they should start planning towards that because it will be bad business if they get relegated after getting this massive buy deal.
It is unlikely that in the coming years, we should expect major victories from Newcastle, even if they have a wealthy owner. The team will essentially start from the beginning. It will be necessary to attract a new coach, after the new players. And the team will need time to reach stable results. In the future, strong players may come to the team who will fight for awards. But this will require a lot of time. Maybe 5-6 years.
I think les than one or two years later Newcastle United will be on top four position in primer league, I think 5-6 years is not happening with Newcastle have much money to get star player and easy less than two year success become top team in primer league. Without participant in EUROPE league I think give one credit for Newcastle how focus on primer league only and take top four position to qualify on champion league next season, most important for Newcastle to get top four position if want to sign many star player.
