Teenage midfielder Ignacio Camacho scored two goals on Saturday to lead Atletico Madrid over Recreativo Huelva 3-0 in the Spanish league.
The win tightens Atletico’s grip on the fourth Champions League qualifying place.
Camacho beat goalkeeper Stefano Sorrentino to a cross in the 23rd minute to head in his first league goal on the eve of his 18th birthday.
He doubled his tally in the 75th after swiveling to score from a loose ball.
Argentina striker Sergio Aguero scored in the 54th after sliding in Maxi Rodriguez’s centering pass.
Atletico are fourth with 58 points, five more than Racing Santander and six better than Sevilla.
“These are all finals. There is no margin for error,” Atletico coach Javier Aguirre said.
Recreativo remain entrenched in the relegation fight in 17th with three games remaining and 40 points — the same as No. 18 Osasuna.
Defender Roberto Ayala scored on the last play of the game to give Zaragoza a 1-0 victory over Deportivo La Coruna to lift them out of the immediate drop zone into 16th with 41 points.
Atletico, winless in three coming in, dominated from the 17th when Sorrentino got down to stop Raul Garcia’s volleyed shot from outside the area.
Aguero saw a goal ruled offside two minutes after Camacho opened.
Sorrentino got a hand up in the 32nd to push Luis Garcia’s hard drive over the goal.
Recreativo defender Martin Caceres slipped to allow Maxi through and the Argentina midfielder found Aguero racing in for his 17th goal of the season.
Florent Sinama-Pongolle’s left-footed shot rolled wide of the far post in the 68th, Recreativo’s first chance.
Zaragoza’s continuous pressure finally paid off in the fourth minute of injury time.
Ayala guided Sergio Garcia’s short pass into the empty goal after goalkeeper Dudu Aouate had come out to play a long ball that got past him.
Though Deportivo arrived at La Romareda stadium on the heels of five straight victories, it was Zaragoza that dominated.
Striker Ricardo Oliveira, who saw a 32nd-minute header saved, shot over in the 54th while Pablo Aimar sent his chance across the open goal and out only a minute later.
Aouate tipped Sergio Garcia’s shot from inside the area wide in the 71st with Diego Milito hitting the side netting from a nearly impossible angle with an open goal begging.
Oliveira was clear through after a number of sharp passes in the 78th but he shot over.
