Chelsea can be the best when terry and cech return they all the "WALLS"of chelsea.Terry provide the clearance and cech can save when terry cant handle...SO buying defender is a waste of money ..Mourinho has been talking about the special ONE...This cause players that are not in the special ONE list to be not playing well for the club...Sheva was new in epl and he try his best as there are different pace in the epl...He need time...when both terry and cech is back chelsea is the BEST
