There are different salary models in the MLS. Before the season, the Whitecaps opted for a model in which only two designated players are allowed to earn outside the salary cap. Team captain Ryan Gauld and Andres Cubas currently fill these slots.
Muller reportedly would only have had the equivalent of €300,000 available within the salary cap for the rest of the season. However, he will receive around €600,000 until winter for two reasons.
The first is through Targeted Allocation Money (TAM), which helps clubs sign players expected to make a strong sporting impact when designated player spots are unavailable. The second is due to the injury of Canadian defender Sam Adekugbe. While he is sidelined, his salary can be reassigned to another player - Muller, in this case.
For the 2025 season, the Whitecaps plan to adopt a salary model with three designated players, with Muller expected to take the third spot. He has reportedly agreed to a salary of €6m for the 2026 campaign.
