I really don't think we do, when you consider the following:
GK: 1. Cech, 40. Hilario, 22. Turnbull
RB: 17. Bosingwa, 35. Belletti, 19. Ferreira, (5. Essien, 42. Mancienne, 2. Ivanovic)
CB: 26. Terry, 33. Alex, 2. Ivanovic, 6. Carvalho, 42. Mancienne, (5. Essien)
LB: 3. Ash Cole, 18. Zhirkov (17. Bosingwa, 19. Ferreira)
CDM: 5. Essien, 12. Mikel, (13. Ballack, 20. Deco, 42. Mancienne, 2. Ivanovic, 35. Belletti)
CAM: 5. Essien, 8. Lampard, 13. Ballack, 20. Deco (7. Shevchenko)
RW: 10. Cole, 21. Kalou, 16. Sinclair, (5. Essien, 35. Belletti)
LW: 18. Zhrikov, 15. Malouda
CF: 11. Drogba, 39. Anelka, 7. Shevchenko, 21. Kalou, 14. Pizarro, 23. Sturridge, 9. di Santo
The players in brackets are just possibilities for cover players when there are multiple injuries. I think we've really got our squad as strong as it can be. And there are young players like Mellis and Hutchinson who might make the first team come the start of the season.
