They might well, but Chelsea can't buy every player, so ultimately the prices come down.
If we were ahead of it we could have gone harder and earlier for Mudryk, tried to force it in summer. The £27m for Saliba is a decent example of how to do business in this environment.
The aspects to be regretted about this transfer are that Mudryk was the right age to be developed in an Arsenal mentality and football, and had the right elite physical attributes. The other regret is that he'll be wasted at Chelsea. We can find targets to match him otherwise.
