WATCH: Joao Cancelo's wild knee-slide celebration as he scores Barcelona's third goal in just eight minutes to complete remontada-esque comeback vs Celta Vigo

The on-loan full-back provided his biggest moment in a Barca shirt yet, poking the ball home off Gavi's cross to seal three points in the 90th minute.

Barcelona had endured a grim evening against Celta, and trailed 2-0 after 82 minutes. But a double from Lewandowski, and Cancelo's late winner sealed a crucial win and sent Barca to the top of the table.

Xavi's side will look to carry the momentum from their comeback victory as they take on Mallorca on Tuesday.
