Barcelona exited the UEFA Europa League after a 2-1 defeat at Manchester United on Thursday night.
After the first leg had ended 2-2 at Camp Nou seven days earlier, Barcelona took the lead at Old Trafford.
Robert Lewandowski converted an 18th-minute penalty kick after Bruno Fernandes had fouled Alejandro Balde.
But United hit back to win 4-3 on aggregate after goals from two Brazilians.
Fred drew United level just after half-time when he shot past Barca keeper Marc-Andre ter Stegen using his right shin.
The winning goal was scored by Antony. It arrived in the 73rd minute and was hit much more cleanly than Fred's effort.
