Atletico Madrid head coach Diego Simeone absolved his misfiring attackers of any blame following Saturday's shock LaLiga defeat to Deportivo Alaves.
Victor Laguardia scored the only goal four minutes in at Estadio de Mendizorroza to inflict a first defeat of the season on Atleti in all competitions.
Atleti had just one shot on target – substitute Angel Correa forcing Fernando Pacheco into a fine save – as Simeone's side missed out on the chance to overtake leaders Real Madrid.
The Spanish champions have now failed to find the net in three of their last four matches, during which time they have won only once in all competitions.
Despite playing a full part against Alaves, who were previously without a point this term, Luis Suarez and recent signing Antoine Griezmann failed to complete a single pass between each other.
Griezmann has yet to so much as register a shot on target in his last seven LaLiga outings for Atleti and Barcelona combined, his longest such run in the competition.
Rather than criticise the likes of Suarez, Griezmann and Correa, Atleti boss Simeone instead insisted it was down to him to find a way to break down a solid Alaves team.
"The responsibility is mine for not having found options to overcome their defence," he said at his post-match news conference.
"When opposition teams defend well, it is difficult to find those solutions.
"It's also difficult when a team like Alaves close you down. We didn't have the speed or ability to hurt them. They deserved the win because they scored and knew how to defend."
Laguardia's early goal came from a set-piece situation, the centre-back getting away from Stefan Savic and heading in Ruben Duarte's corner.
Half of the previous 10 goals conceded by Atletico in the league have now come via headers, excluding own goals, and Simeone accepted his side must improve in that area.
"I don't think the defence is to blame for the defeat because the goal came from a set-piece," he said.
"But if there's a weakness at the back, or when defending set-pieces, then it is clear we will have to study that, work on it and try to correct it.
"We have to keep improving. We had several phases of patient play today and I believe in these players."
Atleti's fixtures do not get any easier as they travel to Milan in the Champions League on Tuesday, then host Barcelona in the league four days later.
Reflecting on a bad run of form heading into that huge double-header, Simeone added: "We always say there are bad moments during a season and this may be one of them.
"We have a good squad, a balanced squad, and we will analyse what is going wrong and try to find solutions."
