Marcus Rashford has endured a difficult evening after he was immersed in his first start for Barcelona during his first start.
The England attacker joined the Catalan side of Manchester United last month, with an option to make the deal permanent for around £ 30 million.
He made his Leaga debut of the bank last week when Barca rode a 3-0 win over Mallorca on the opening day of the season.
And the 27-year-old made his first start against Levante on the left wing, with Raphinha in the middle behind Ferran Torres and Lamine Yamal on the right.
He had an early half chance after he took a corner that was cleared back to him.
Rashford got into the box and had a Snap shot that forced a comfortable rescue from home keeper Pablo Campos.
The United Loeninge did not succeed in having a significant impact, because Barca went 2-0 in the first half.
He was picked up during the break next to Marc Casado with Dani Olmo and Gavi who took their place.
Barcelona had fallen behind after 15 minutes when Ivan Romero found space in the area and ended quietly past Joan Garcia.
Jose Luis Morales then converted from the place to have Double Levante's lead on the rest of the break after Alejandro Bald deemed to have treated the ball.
Barca, however, stood in flat terms within seven minutes after the replacement of Rashford thanks to goals from Pedri and Ferran Torres.
The turning point was sealed in the first minute of added time when Levante's Unai El Manabal diverted the dangerous cross of Lamine Yamal in his own network.
