I can't believe people think we're alright for strikers. Look at the evidence. With Jelavic were a midtable side. Without him we're absolutely awful.
N'Doye is good and has given us another option but we need both of them fit. Even then, when one has to come off in the second half we lose our lead every time, and then can't get back on the front foot. Sunderland is a perfect example of that.
Hernandez still needs to come good, and even when he does, this season shows you need plenty of decent cover up front. Roo is right that Aluko and Sagbo don't count at all. Not even as 4th choice.
People say it's the midfield but we create and score enough when we have decent strikers on the pitch, then we create nothing without them, with the same midfield. It's bleeding obvious what the problem is there!
