Substitute Nico Gonzalez scored a late winner as Barcelona edged past Elche in La Liga to end their three-game winless run in all competitions.
It means Xavi’s side sit seventh, three points off a Champions League spot and 15 behind leaders Real Madrid.
Barcelona had failed to win their previous three outings, with a 2-2 draw at Osasuna last Sunday following defeats by Bayern Munich in the Champions League and Real Betis in La Liga.
