Thomas Partey has penned a new deal to 2023.
The midfielder inked terms this week.
"I deserve what is happening to me," he explained at the renewal's press conference.
"The team works well and individually I'm contributing more than ever.
"I have the confidence of the coach, I've worked hard and must continue in this way."
Atletico Madrid head to the Camp Nou on Sunday with the chance to go within two points of Barcelona should they emerge victorious, Partey believes all matches are equally important however.
"All matches are equally as challenging for us," he admitted.
"We're ready to compete. We have to be strong and fight for each ball as if it were the last."
