Saying we spent a lot on players is true but should we consider when all this happened?
That's exactly what Moses's link does. It converts the value of historic signings at todays rate. £30m 10 years ago in real terms is considerably more than £30m today. There's more money in the game now than there was 10 years ago and as a result transfer values are a lot higher than they were.
Your are mentioning players we signed 10 years ago, my point being City spent pretty much double what we have in the last 3 seasons.
City have spent fortunes but they were/are catching up on the squad building that others have done over a longer period. What's more relevant - how much City have spent in the past couple of years compared to Utd or the total cost of each squad?
