Italia 5-1 Parma, who beat the Italians 3-2 in the first leg at Stadio Olimpico, remain top of Serie A. It was the second time this season the two sides have met.
Parma have a better record at home.
Parma scored twice in the second half to move into second place and are now eight points clear of second-placed Udinese.
The visitors have now gone five games without a victory.
They have lost their last four Serie A games.
“We are looking forward to tomorrow,” Parma boss Mauro Icardi said.
The game started on a sour note as Parma suffered a penalty shoot-out defeat to Sassuolo.
The Viola were also unable to get through the second-tier competition as they finished bottom of their group with a point.
However, the result gave Parma a two-goal cushion and made it a difficult match to lose.
Barca have lost six of their last seven games.
