Joao Cancelo's late strike snatched a 3-2 comeback win for Barcelona against Celta Vigo in Saturday's La Liga clash.
Celta led 2-0 with just 14 minutes remaining thanks to goals from Jorgen Strand Larsen and Tasos Douvikas.
But within the space of four minutes, Robert Lewandowski struck twice to spark hopes of a comeback.
Cancelo then completed the dramatic turnaround in the 89th minute when he drilled Gavi's cross past Ivan Millar.
The result moves Barcelona to the top of La Liga thanks to a superior goal difference over second-place Girona.
However, Real Madrid could return to the top of the table and move two points clear of Barca if they beat Atletico Madrid in Sunday's Madrid derby.
