Jonny levelled the tie against Barca
Barcelona were only in the lead for nine minutes against Celta, who levelled the game on the stroke of half time.
Celta picked the ball up down the right wing and the finish will not have been easier.
Maxi Gomez, who had been at the centre of most of Celta's forward work, beat his man, Lucas Digne, and centred the ball.
Jony was waiting, underneath the crossbar, and could not miss once the ball had evaded ter Stegen in goal.
It proved to be the final action of the half, as the referee blew up straight after.
