As the previous poster alluded to which i replied to, his post showed the net spends of both clubs being low.
Those 2 signings you point out were bought from the funds they got from Coutinho, if they were not then why is Klopps net spend at £50 million since he's been there when those 2 players cost £75 million and £65 million which is £140 million combined.
You do understand that Chelsea and City spent that money with hardly selling anyone, do you know that City's net spend in the last 4 seasons is, over £500 million, Pep's net spend alone in the last 4 transfer windows is almost £400 million when he bought 2 GK's 5 defenders Gundogan Mahrez Bernardo, with hardly any players of value sold.
United in the same time span is just under £500 million with Mourinho.
Abramovich first transfer window in summer 2004 when Mourinho just arrived they spent around £250 million net signing Cech, Robben,Drogba , Carvalho, Duff, SWP, Kezman, Ferriera, Makelele.
I hope you understand the terms of net spend and financial doping now mate.
