The CB situation is a difficult one-
Agger- no problems here, but going on past history, can't be relied on to play every game (unlike Hyypia, Carra)
Skrtel- may have some concerns about future after being dropped, but probably should still be kept- just into his prime...
Coates- The real problem. Can't really be played other positions and wants games, but probably isn't ready to be first choice yet- maybe needs to be sent on loan as a best solution for now?
Kelly- Could be ready to provide back up option, but won't be an option all the time
Wisdom- Unlikely to be ready for CB action next season...
Therefore we needed at least one more option-
Step up Kolo Tuore, he is ready to provide a CB option next season, sort of like Kyrigiakos (sic), after Hyypia left, but hopefully better.
Maybe he can also provide an option at fullback or cover for Lucas, but mainly at CB, allowing Coates to leave (hopefully only on loan) and allow us to maybe invest in another younger CB, who would be eased in over time (delaying a decision on Coates/Skrtel/anyone else).
Experience is required at CB, so having the option of including an experienced player next to a youngster (in the cups etc..), makes sense. Otherwise, signing Kolo would make no sense at all, and initially i have my doubts. However, who knows, he could settle in nicely and challenge for first choice (depth is important) .
