The first goal was shrouded in controversy as it clearly went over the endline before Lucas Digne clipped it towards Deulofeu.
"I didn't see a problem," he explained to BeIN Sports. "I still have not seen a replay of the incident, but for me it was legal.
"I believe this, hence why I played on."
Luis Suarez continued his poor domestic form on Saturday evening, even missing a clear open goal just before he was withdrawn by Ernesto Valverde. Deulofeu doesn't feel there is any reason to panic over the former Liverpool forward's form though.
"The goal will come," he intimated. "It is the same if it was [Lionel] Messi, there may be one match without a goal but then in the next one they will score two or three."
