The Belgian international has been linked with both Barcelona and Chelsea in recent weeks after it became clear that the 2015 signing from AS Monaco has a release clause in his current deal in the region of £34m.
However, Atletico are said to be in the process of offering the 23-year-old a new long-term contract and following his treble against Granada, Simeone has lavished praise on the attacker.
"I'm very happy for him," Simeone told reporters. "It's been a daily struggle for him to be what he was in this match. He's a very complete player, with very good scope for growth. He can be whatever he wants to be, he listens, has goals in him and is brimming [with quality]."
Amid talk of interest from Barcelona and Chelsea, Carrasco said that he was 'happy at Atletico' when questioned on his future last week.
