Barcelona have gained their first points in the Champions League, defeating Dynamo Kiev through a Gerard Pique goal.
But a relatively sparse 45,000 crowd in Camp Nou was unimpressed and whistled their own players.
After consecutive 3-0 defeats to Bayern Munich and Benfica, Barcelona entered matchday three bottom of group E and in desperate need of a result.
Pique's 36th minute volley, from fellow defensive veteran Jordi Alba's cross, kept their last 16 hopes alive with a deserved if uninspiring win.
The goal was Pique's 16th Champions League goal, drawing him level with former Real Madrid left back Roberto Carlos as the top-scoring defender in the competition's history. The 34-year-old Pique also became the oldest Champions League scorer for the Catalan club.
But coach Ronald Koeman's embattled side laboured throughout even against lethargic opposition and enter the weekend Clasico with Real Madrid in low spirits.
Group leaders Bayern, on six points, are without coach Julian Nagelsmann due to illness when they visit Benfica later.
In group G Red Bull Salzburg opened the scoring against Wolfsburg through Germany forward Karim Adeyemi and a second-half double from Noah Okafor earned a 3-1 win after Lukas Nmecha's equalizer.
Salzburg are on seven points to top the section with Wolfsburg third on two, behind Sevilla on goal difference. The Spaniards later visit French champions Lille, who are bottom on one.
Other late kick-offs include holders Chelsea hosting Malmo and Manchester United welcoming Atalanta.
