Atletico are currently fourth in LaLiga on 41 points, eight behind leaders Barcelona after 20 games played.

They are currently unbeaten in four matches in the league, but the off-the-field talk is all about Alvarez, who has been linked with a move to Arsenal and Barca and has struggled in front of goal.

Without a LaLiga goal in nine games, more onus will be placed on Alvarez on Sunday as Antoine Griezmann is set to be sidelined through injury.

And Simeone was quick to throw support behind his compatriot when the forward's ability was questioned.

"Seriously? Are you seriously asking me that?," Simeone told reporters.

"The truth is that Julian Alvarez speaks for himself, because of the name he has, the authority he carries, and the career he's built, right?"

While Atletico are on a strong run in LaLiga, they have struggled for goals in the last few weeks, failing to net more than once in any of their last three matches in all competitions, having drawn 1-1 with Galatasaray in the Champions League in midweek.

Mallorca, though, have problems of their own, sitting 16th in the table, though they did beat Athletic Club 3-2 in their last outing.

Simeone has won 13 of his 15 LaLiga matches against Mallorca's Jagoba Arrasate (D1 L1) – no other manager has won more times against another in the entire history of the competition.

And the 55-year-old is determined to end their scoring troubles against Mallorca.

"The absence of a player like Antoine Griezmann is always felt, whether he starts the game or comes on as a substitute, as he was doing, but it's clear that he's always a very important player for the team," Simeone said.

"As we explained after Wednesday's match, always interpreting that final phase in the best possible way makes you stand out, and surely, with hard work and the energy and commitment that the team has, we will find possibilities to increase our scoring, which is what the game is all about."
