Knn, Singapore and Malaysian billionaires know fark all about football let alone how European clubs work. Look at Vincent Tan and the Fernandez guy who buy Cardiff and QPR... all first year kenna relegated. Football is not in our DNA. We can't play football at the level and we can't even buy and manage proper football clubs. Vincent Tan thinks changing from blue to red attire will keep Cardiff up... this kind of mentality? People are talking about tactics, talent, strategy... we talk about superstition.
PL will get a rude awakening when Valencia kenna relegated after next season.
Owning a football club is a very unique business. You can splash a lot of cash and yet achieve nothing e.g. QPR, Cardiff.
I can see a lot of these Asian owners are very kiasu, they expect miracle results within one season when it should have been a long term project.
First of all, you must hire a good football manager and be on good terms with him. Don't try to play politics with him.
Your scouting network must also be good. The Asian owners tend to overpay for not-so-good players, and buy plenty of them at one go without addressing the team's needs (QPR and treatment of Joey Barton). It's not like playing a FIFA video game where you simply swap existing players with ones that have higher stats. Some players are not bad; rather, they can't play well in a certain system. You'll have to decide to keep the player or the system.
Next, you have to develop your youths within your academy. The ones that are really good can break into the first team. The better ones but not good enough to break into the first team can be loaned or sold. Sometimes some players are late bloomers who may shine during their loan spell. Keep tabs on their development.
The financial side of the business: players' wage bill, stadium ticket receipts, sponsorship deals, tv broadcast revenue, merchandise sales etc. Try to avoid having long term contracts with players aged 30 and above. A player's performance (and market value) peaks then declines after his late 20s.
Last but not least, invest in good medical facilities and have a good medical team. I'm not naming any clubs here but some clubs have plenty of injuries, players who go in and out of injury rehab, and whose fitness are questionable after recovering from an injury.
