The frustrating part is that other than Morata, who failed spectacularly, and Costa, who did well, the club has not signed a first-choice striker in about 7 years. You'll have to go all the way back to Torres in 2011. I am sick of temporary solutions - Ba, Eto'o, Remy, Drogba (second time), Falcao, Pato, Giroud. (Not including Michy since he was a young prospect)
Only reason, I would be okay with another stop-gap is because good strikers may not be available in January to be signed. This summer, the club desperately needs to bring in a quality striker
