Chelsea boss Mauricio Pochettino admits they missed Armando Broja for defeat to Brentford.
Pochettino concedes they're short of options in attack.
"It's obvious at the moment, no. So far, no," he said.
"Bad luck. [Christopher] Nkunku that proved he can score in big leagues like Bundesliga was injured in the last pre-season game. This type of thing did not help.
"Then we need to recover [Armando] Broja and different circumstances Nicolas Jackson was affected for different reasons, but he's young and arriving this season and needs time to adapt. Of course, that is obvious, and your analysis and some point, I think we agree."
