Barcelona will be particularly wary of Valencia's visit after a more mediocre version of the same side fought back for a 3-2 victory at Camp Nou last season.
That loss on Feb. 1, 2014, marked the beginning of Barcelona's slide and allowed Atletico to take over the league lead.
Valencia has a much better, and deeper, squad this season. Coach Nuno Espirito Santo has the team in fourth place, only one point behind Atletico and three points ahead of Sevilla as they vie for a top-four finish.
Barcelona midfielder Andres Iniesta is doubtful after he was carried off the field in Paris.
Valencia will likely be missing injured Argentines Enzo Perez and Pablo Piatti, but left back Jose Gaya is fit.
"Barcelona is the clear favorite because it is playing at home," Valencia goalkeeper Diego Alves said. "But we will try to play a good game and challenge for the win."
