Atletico Madrid believe Diego Costa's wage demands from earlier on in the season are now behind him.
The 30-year-old is currently out of action because of a hamstring injury, with the aggressively-natured forward yet to register a goal in La Liga during this campaign.
It is said that Costa currently earns £7m-a-year at the Wanda Metropolitano, but he wanted an increase to reduce the big wage difference between fellow strike partner Antoine Griezmann.
The France World Cup winner is reportedly earning £17.5m-a-year, with his club keeping hold of their star man over the summer after a number of mooted transfers.
Costa has already enjoyed success under the defensively-sound Diego Simeone this season when they beat rivals Real Madrid in the European Super Cup in August.
Simeone's men netted four goals, two of them from Costa, as they saw off their neighbours in extra-time to claim their first silverware of the season.
