On Tuesday, the Portuguese international will be looking to help his team bounce back from their opening Champions League defeat to Bayern Munich when Atletico host RB Salzburg.
"It's always the same. For me, he's had some very good games since the start of the season," Simeone said when asked about Joao Felix in his press conference. "Granada, Huesca, Villarreal despite being tired, the whole game in Munich...
"He's looked dangerous on a number of occasions. The other day [against Real Betis], when he came on in the 25th minute, the team had a good fluidity.
"I'm happy with his work, except for a few minutes against Celta [Vigo], which weren't the best. We're always looking for a situation to find him [on the pitch].
"He's a boy who's in good form, like many of his teammates."
