Barcelona made it three games without a victory on Thursday as a goalless draw with Cadiz further weakened Ronald Koeman's position as coach.
Frenkie de Jong was sent off in the 65th minute at the Ramon de Carranza stadium but holding on for a draw will earn little credit for Koeman, who was also shown a red card in injury-time.
"You have to always try to win each game, but you have to be realistic, you have to see the squad we have, the people we're missing," said Koeman.
Barcelona are already seven points behind La Liga's early leaders Real Madrid, albeit having played a game fewer, to go with a poor start in the Champions League after last week's 3-0 opening defeat by Bayern Munich. A 1-1 draw with Granada on Monday did little to boost morale, with Koeman coming in for heavy criticism after finishing the game with central defenders Gerard Pique and Ronald Araujo up front.
Disappointment with the team's style and doubts around his future prompted a defiant reaction from Koeman in a press conference on Wednesday.
He refused to answer questions, instead reading out a statement that asked for patience and insisted the process of rebuilding the team "deserved unconditional support".
That was taken as a clear message to club president Joan Laporta, who was reluctant to be drawn on Koeman's future before the match against Cadiz.
After the match, Koeman said: "He was in the hotel and we said hello before the match. I'm sure there will be more days to talk if the club wants to talk."
The game turned wild in the final minutes as the ball flew from one end to the other.
Philippe Coutinho spurned a late free-kick, Salvi's close-range finish was blocked and as the clock ticked into the 94th minute, Depay fired just wide of the far post.
In the madness, Koeman was shown a red card as well, the Dutchman smiling at the final whistle with a face of disbelief.
