But they shouldn't because ultimately it's spread X amount of years where we'll continue to increase and generate record levels of revenue that will allow us to not only pay players more but spend more money too.
The value of a player is how much the club ask for him. All the other feed and stuff will be offset over a period of however many years that won't actually put a dent in the clubs pockets. So long as we're not spending 300k a week and spending £100m on a single player than it's going to be affordable for us.
And if Wenger wants to talk about Costa costing £100m well he's been pivotal in two titles in three seasons which represents a pretty healthy investment.
