Selling team wage contribution

Hi everyone. Need a little help understanding the wage contribution system when buying a player.

I’m the manager of Nantes in 2024 and I’ve just bought Koke from PSG for 5 million Euros + a wage contribution of 1 million Euros until 2025. We agreed on wages around 150k per month. Does this mean that after 2025 I’ll have to pay his current wages plus the contribution he was receiving from PSG or I’ll keep paying his normal salary?

Cheers.
