Is Ange right? Are injuries the only reason for Spurs' slump?

Dan Kilpatrick, Tom Allnutt and Tom Barclay were all at Villa on Sunday as Spurs crashed out of a second cup competition in four days and they all questioned Ange in a fiery post-match press conference. Is the manager right to accuse his critics of "skewed", "agenda-driven" analysis and suggest that injuries are the sole cause of his side's woeful form? Or is there more he could have done in the circumstances, dire as they are? The panel get stuck in and don't always agree.
