Antoine Griezmann says he's never been happier after scoring twice in Atletico Madrid's win at Real Betis.

Griezmann, who signed permanently for Atletico this month from Barcelona, scored both goals for the 2-1 win on Sunday.

He later said: “I try to do everything possible to improve by working on defence, scoring goals or giving assists.

"I feel very well and it is my happiest stage at Atleti. This level is what the coach and my teammates need. I will always leave everything to help my team.

"It is an important victory. We had lost two points against Rayo Vallecano and we had to win this game. It has cost us but we have worked well in defence."
