Arsenal boss Unai Emery has eased fears over Dani Ceballos' injury setback last night.
Emery says the hamstring injury he picked up against Vitoria was a 'small' one.
Ceballos was substituted shortly after he pulled up clutching his hamstring early in the second-half of the Gunners' 1-1 draw with Vitoria in the Europa League on Wednesday.
Speaking after the game Emery said: "We are going to wait for the analysis tomorrow but, at the beginning, I think it's a small injury."
Ceballos has become a fans' favourite at the Emirates, making 15 appearances in all competitions since his loan move from Real Madrid , but he could not help inspire his side to a victory against Vitoria as the Portuguese side scored a last minute equaliser.
