Atletico Madrid head coach Diego Simeone said anxiety prevented his team from scoring in their goalless draw at Villarreal.
Simeone's Atletico failed to win for the third consecutive LaLiga match following Friday's stalemate away to Villarreal.
It was another toothless showing by sixth-placed Atletico, who have only scored 16 goals through as many league games this season.
"It is normal that when you generate so many chances and do not convert, anxiety appears," Simeone told reporters. "And more anxiety, less precision.
"When anxiety disappears, tranquillity and precision will come from the players we have. Today we had clear occasions, Joao Felix and [Renan] Lodi's, but we did not define them correctly."
Atletico could end the weekend seven points adrift of third-placed Sevilla and eight behind leaders Barcelona.
"At the moment, what worries me is to win a game and everything will be looked after in a different way," Simeone said.
Atletico captain Koke added: "In front of goal we have no fortune, precision or I do not know what is missing. To win you have to score goals.
"The team defends well, gives everything, but we need to be more precise to all, the strikers, the midfielders, the defenders..."
