Liverpool's squad is filled with players that needed a lot of transfer funds.
Chelsea's squad is even more coupled with money for the player's huge salaries.
Man Utd's squad is no different with big buys in Tevez, Anderson, Nani, Berbatov and huge salary pay packages.
Arsenal squad is filled with buys comparatively to the above teams, is considered petty cash to them.
City squad is going to be changed when transfer window re-opens.
The common thing is all have foreign ownership except Arsenal. In terms of consistency, Arsenal is most shrewd. But if want to talk about winning championships, Arsenal will need to allow themselves to be taken over by a foreign group. Only with huge injection of funds, will they be able to top the league every season because their best players will not leave due to low pay package.
It's just a matter of time.
