How much do Pogba and Sanchez earn in comparison to KdB and Aguero?
You have to factor in that media quoted figures for Utd wages usually include all bonus payments. This is irregardloss of whether targets are met & the bonuses are actually paid. City figures tend to be reported as a basic salary with bonus payments that could occur.
Pogba & KDB both earn £280K P/W. In the case of Pogba this is his top line wage with bonuses paid. KDB's new contract gives him a flat £280K with an extra £70K P/W in bonus payments. It is likely he won't reach all his targets so the payment will be slightly less. He is though earning considerably more than Pogba. Image Rights can muddy the waters slightly. These though should not really be considered in the grand scheme of things. Pogba will likely be earning more than KDB in this respect. He is though a more marketable player. These payment won't really be costing the club money as he is bringing more in than what he takes out.
Sanchez & Aguero will also be on much the same wage. Aguero earns a basic £220K with a further £80K per week in bonuses. The crazy figures the media report for Sanchez go from £500K to £600K. These figures though include the signing on fee, agents fee & all bonuses paid. Take all these off & the wage is obviously a lot less. It's obviously not a great headline though stating ''Sanchez signs deal as big as Aguero's'
I wouldn't put too much stock in the wage figures your club reports though.
My local rugby team Salford were in much the same position as City. A Yo Yo team, with large debts, going nowhere. Salford were bought out by a wealthy owner who wanted to play Rugby Manager on cheat mode. The club moved to a new stadium & started making lots of expensive signings. The problem was that Rugby had a salary cap. The club were investigated & it was found that the owner had been buying players expensive cars, houses etc etc to supplement there wages. The club were docked points as a result. This is very much what is going on at City. The difference is that City will get away with it as there are no rules on what club owners are allowed to give players.
