Victor Roque issued a notice to Barcelona before facing his parent club The League action this weekend.
The Brazilian international has shown flashes of form during his loan spell The Real Betis but a clash with the league leaders poses a different challenge.
The 19-year-old shook off a minor knock and should have led the hosts' attack at the Estadio Benito Villamarin.
Hansi Flick offered his point of view on the striker, after his controversial loan exit at the beginning of the campaign, with the German claiming that it was for the best with the unhappy striker in Catalonia.
Before the game, Vitor Roque confirmed that he will not celebrate if he scores against Flick's charges, but is confident of finding the back of the net.
“If I score a goal against Barça, I will not celebrate, out of respect,” as Gol TV, via AS Diary.
“I face this match like any other. I see myself scoring, God willing, because that's what I'm working on all week.”
Vitor Roque has five goals in all competitions for Los Vediblancos, but has not scored in almost a month.
