Diego Simeone is convinced Joao Felix "can go far if he wants to" despite struggling in his first season at Atletico Madrid.

Joao Felix became Atletico's record signing when he arrived from Benfica for €126million in pre-season, coming in as Antoine Griezmann's replacement.

But the Portugal international's impact has not been as significant as expected, scoring just three goals in 19 LaLiga appearances, having also missed a chunk of the season through injury.

Atletico face a fight to qualify for a Champions League spot, as they sit fifth behind Getafe and Sevilla – their visitors on Saturday – in the battle for a top-four place.

Simeone remains a believer in Joao Felix's abilities and potential ahead of a crunch clash with Sevilla on Saturday.

"He started with great enthusiasm," Simeone told reporters on Friday. "He had two injuries that took him out of that continuity.

"He is looking for that continuity in the team again, that continuity we all need and expect from him.

"Hopefully he gets to where he suggested he could, because in the case of young boys it is a consequence of where one wants to go. If he wants to go far, he can."

Like Joao Felix, Diego Costa has also recently returned to fitness and could play a significant role in the final weeks of the season, with Simeone optimistic about the striker's condition.

"I see him growing, looking for his best state, training accordingly to want to improve," the Atleti coach continued.

"He was never a great header, his game was more direct, more vertical, more positional. He felt comfortable in the game [against Espanyol].

"I see him [getting] better. He could not show all this the other day, but it is a phase of his recovery and we can count on him."

The visit of Sevilla comes just four days before Atletico's Champions League last-16 second-leg clash with Liverpool at Anfield, where Los Colchoneros will start with a 1-0 lead.

But Simeone insists his one and only focus is the Sevilla match, knowing victory will move them back into the top four and above Julen Lopetegui's erratic side.

"We do not look five days ahead, only Sevilla," he said. "We have the need to make an important match. Sevilla is strong away from home, signed new players [in January] like Suso that give quality in attack.

"The importance of the match is clear. Sevilla is a dangerous team away from home - they move better with spaces for their fast players in attack. That's where they perform their game best.

"Both matches are important - we are excited. It's a football week, in which we prepare to reach important targets. We have a beautiful battle ahead."
