(REUTERS) - Influential forward Antoine Griezmann has extended his contract with Atletico Madrid by one more season, which will keep him at the club until 2021, the Spanish La Liga side said on Thursday.

The 25-year-old, who joined the club from Real Sociedad in 2014, has flourished under manager Diego Simeone, scoring more than 50 goals in his two seasons at the Vicente Calderon.

Griezmann also guided Atletico to their second Champions League final in three years, but missed on the prestigious trophy, both times to local rivals Real Madrid.

"I'm very satisfied, very happy to keep belonging to this family and this project," the France international said on the club's website (en.atleticodemadrid.com).

"I want to improve every year, and the club, the coaches and my team-mates can help me to reach this goal."

Griezmann, who was heavily linked with a move away from the club, is currently part of France's Euro 2016 squad and scored in his country's 2-0 group-stage victory over Albania.

The hosts play the Republic of Ireland in the round of 16 in Lyon on Sunday.
