Atletico Madrid can take over at the top of the Primera Division this weekend and coach Diego Simeone is demanding another committed display against Levante.
The Rojiblancos are currently tied with Barcelona for first place but can get the drop on the Catalans, who visit Getafe on Sunday, by earning a single point against Levante at the Vicente Calderon nearly 24 hours earlier.
Atletico have won three league games in a row - they have lost only once this season - and further demonstrated their trophy-winning credentials when coming from behind to beat Sant Andreu in the Copa del Rey in midweek.
It was a feat that thoroughly impressed their Argentinian boss and he told the club's official website: "I am delighted by the response of the players and all the commitment they have shown. They demonstrate it week after week.
"Atletico fans will be very happy about the players' commitment, they share the same ideas and when people are united with the same ideas it is very difficult to compete with them."
Should the Madrid club pull away three points clear at the top with victory on Saturday then Barca will need to beat Getafe at the Coliseum Alfonso Perez, something they have managed to do four times from five recent visits.
Real Madrid, meanwhile, are five points off the pace and travel to Valencia ahead of Nico Estevez's first game in the Mestalla dugout.
With Los Che nosediving in La Liga, Miroslav Djukic was finally sacked this week to leave youth coach Estevez in interim charge, and Real midfielder Asier Illarramendi is determined to hand the rookie coach a nightmare debut.
"We cannot slip up any more in the league, so we have to win in Valencia," he said. "But every team that plays against Real Madrid are highly motivated and give more than 100 per cent."
