Diego Simeone sees no problem with Atletico Madrid's players celebrating their victory over Liverpool, though insisted he has not let his squad get carried away.

Atleti will take a 1-0 lead back to Anfield after Saul Niguez's early goal gave them a win in the first leg of their Champions League last-16 tie against the Premier League leaders and defending European champions.

Clips were subsequently shared on social media following Atleti's win of their players celebrating the triumph during a recovery session.

This is no issue for Simeone, though the Argentinian – whose side sit fifth in LaLiga ahead of Sunday's clash with Villarreal – left little doubt that his team must keep their feet on the ground.

"I have always said that extremes are bad," Simeone told a news conference when asked about the criticism Atleti had received for celebrating their win, with Liverpool defender Andy Robertson having suggested the Spanish side were acting as if they had already won the tie.

"There are no extremes in the locker room. We have seen that people lived with the negative results and when we see positive results the opposite happens.

"But we know that LaLiga is long, that the Champions League is very hard and the balance is in maintaining consistency.

"In the same way that I am saddened by defeats, we must celebrate the victories. Liverpool was a first half. The second one remains."

SAUL TO CRITICS: "WE'RE GOING TO WIN OUR WAY"

Joao Felix has been included in the squad for Sunday's match and Simeone is thrilled to be able to have his record signing back in the group.

"What excites me is that they are all in the squad. That generates internal competition," Simeone said.

"When Joao Felix and [Diego] Costa have been away, [Angel] Correa and Vitolo played and this generated a lot of internal competition.

"It also happened with [Jose] Gimenez and [Stefan] Savic, with Felipe and [Mario] Hermoso. This internal competition generates growth and improvement."
