The decision came on a penalty kick in the 97th minute. Lewandowski scored both of Barcelona’s goals in the away game in Vigo.
The Pole initially missed the penalty, but had to take it again as Celta’s goalkeeper did not have at least one foot on the line.
Just before the break, Lewandowski put the visitors in the lead, but Celta hit back a few minutes into the second half. Iago Aspas made sure of that with a shot that changed direction and put Barcelona’s goalkeeper Marc-Andre ter Stegen out of action.
Just over a week ago, the reigning La Liga champions were held to 3-3 at home against Granada. On Saturday, they were very close to losing by a point against a bottom team.
The overtime victory took Barcelona up to 54 points and a small gap to fourth-placed Atlético Madrid. There are seven points up on league leaders Real Madrid, who have played one game less.
Jørgen Strand Larsen started in the Celta attack and played 85 minutes. The Norwegian’s team is only three points above the relegation zone.
