You have forgotten about Arsenal. They have spent massively the past 2-3 seasons. Or do you think they flatter to deceive?
I'm not a huge fan of Arteta honestly but they're a big club obviously I don't think with Arsenal the owners are going to compete with the others still. Kroenke is a businessman and I don't really think he cares too much really, Arsenal gets attraction because they're London based. This summer they've made some very good buys but I don't think Arsenal will compete with Liverpool or City for that matter right now.
I think Spurs are better right now, especially under Conte.
My main fears honestly is over this decade United can't just slip away though. City, Newcastle will be mammoths Saudi will pour billions into making Newcastle a superpower because of the oil states: Qatar (PSG) , Saudi (Newcastle), UAE (Man City) it's a PR campaign for them. I lived in Dubai for 6 years and you see how they invest in infrastructure in general they don't really have to limit spending because the money literally comes out of the ground. It's a way for them to get tourists to the countries, Etihad and Emirates owned by the Sheikhs literally have a way to brand the stadiums (Etihad and Emirates respectively) so the names everywhere and then you fly with the airlines and you have to stop over in the UAE so they've done really well. Tourists flock to Dubai now.
Newcastle under Saudi will do the same, they're opening more to tourists now and the majority (historically) was for Haaj (the religious pilgrimage) now they want to cater to more people. So the Newcastle buy (they wanted United) will be a way to do that. They'll throw billions into infrastructure making Newcastle a huge team, sponsoring themselves like City did effectively. I can pretty much guarantee they'll want Saudi Airlines to compete with Emirates and Etihad too because they want to prepare for post-oil economies and football is a great way to get exposure for people to visit. Watch the next decade unfold, who sponsors Newcastle, what the stadium will be called. It's completely PR and advertising for the state. So Newcastle will be a huge team this coming decade IMO.
It kills sport and it's sad but money is money of course.
They will be a Man City and go beyond what Chelsea have done IMO, getting Madison for them is just the start of drawing the next tier of players to them. No real assurances over Liverpool because when Klopp goes I think it'll be hard for them to replace him as a manager but the next decade you have what? City, Newcastle, Chelsea, United, Liverpool, Arsenal, Spurs.
7 teams for the top 4, the Premier League will be beyond difficult. I genuinely hope Murtough, the Glazers can make the right decisions and ETH I hope can restore the club to be challenging because rivals won't stand still for sure.
As a United fan for my entire life I just really don't want another decade of the same, because it's not a two horse race anymore, it's going to be a six horse race.
