Barcelona missed the chance to cut the gap to LaLiga leaders Atletico Madrid to six points as a late penalty gave Cadiz a 1-1 draw at Camp Nou.

Lionel Messi marked a club record 506th league appearance with the opening goal from the spot in the 32nd minute.

That appeared to be enough to give Barca an unconvincing win, but a dreadful week for Ronald Koeman's side ended in fitting fashion.

Clement Lenglet was ruled to have clipped Ruben Sobrino in the area and Alex Fernandez emphatically converted from 12 yards in the 89th minute to earn a share of the spoils.
