Welbeck signed on a free transfer after being released by Arsenal at the end of last season.
Gracia will be hoping that he can count on the Englishman to add much needed quality and pace to his attacking line.
Speaking about injured players, Gracia said to reporters: "[Ismaila] Sarr, I think he needs more time, Welbeck maybe is not in the best condition, but he could help us this weekend if we need him for some minutes.
"This week we have some little problems, but I think all of them are ready. There's different situations for all of them but I don't have any player injured.
"[Roberto] Pereyra and [Gerard] Deulofeu are better. Roberto because he's had five training sessions more and he needed it. Gerard in this case is better because he had a small stomach problem before the game, but now he's recovered."
