Atletico Madrid's lack of preparation time has not dampened Diego Simeone's confidence ahead of Sunday's clash with Real Madrid, with the Argentine hoping their past derby successes can provide inspiration.

Atleti are unbeaten through their first seven games of the season in LaLiga, winning four and drawing three to sit third in the table, two points behind their cross-city rivals.

Los Colchoneros have, however, had two fewer days to prepare for the first Madrid derby of the season, having beaten Celta Vigo 1-0 on Thursday. Carlo Ancelotti's champions, meanwhile, downed Alaves 3-2 on Tuesday.

Atleti do boast a strong record against Los Blancos, being the only team to beat them in any competition last season – once in LaLiga last September and again in the Copa del Rey in January.

Simeone has masterminded 12 wins in his 43 Madrid derbies as Atletico coach (15 draws, 16 losses), as many victories as they managed in their previous 77 prior to his arrival.

Speaking at Saturday's pre-match press conference, Simeone told reporters: "A lot has changed up to this moment. 

"It's an aspect in which we’ve improved, and that’s why the club has grown as it has, and the team is held to the standards it is.

"Everything starts in the mind. Beyond the physical aspect, which can have an influence at times, motivation is an important weapon for everything in life."

The Argentine did admit the lack of preparation time posed a unique challenge, adding: "It's tough to change things in two days, based on what we've been doing.

"We are still in the process of finding our balance, we are adapting and we get it right more or less. But it is true that we need more time.

"We accept it as it is. We said it before when we went to play against Athletic Bilbao in the (Copa del Rey) semi-final, them with five days and us with two days of rest. No-one cares."

Atleti's only home defeat so far this year came in February's Copa del Rey semi-final against Athletic, who went on to win that trophy.

While Madrid have plenty of firepower despite Kylian Mbappe missing out due to injury, Simeone feels Sunday's visitors will miss the influence of retired midfielder Toni Kroos.

"The opponent has lost a very important player like Kroos," he said. "I think they are looking for that player who gives them that calm to take advantage of all their offensive power."
