What a major Isak-style signing would mean for Arsenal
A big fee does not hit the rules all at once. The annual transfer-fee cost, wages and football income decide the real spending-room impact.

Spread across the contract for annual squad-cost purposes.
Longer contracts reduce the annual transfer-fee cost.
Annual wage input for the scenario.
The quick read
A major signing does not reduce spending room by the full fee in one season. The fee is usually spread across the contract, then wages are added on top.
That means a GBP 150m signing on a five-year deal starts with an annual transfer-fee cost of about GBP 30m before wages, agent fees and signing costs.
Why the contract matters
The contract length is one of the biggest accounting levers. A GBP 150m fee over five years is very different from the same fee over three years.
Supporters often talk about the headline fee. PSRwatch focuses on the annual squad-cost effect because that is closer to how the new live rules work.
What this means
For Arsenal, the question is not simply whether the club can pay the fee. The better question is whether the annual fee cost plus wages still leaves enough room before the Premier League limit.
