One conclusion : Chelsea are afraid of Liverpool's midfield
.
We did , our midfielders was wonderful last night .
Another anlaysis , he played Ferreira cos he want to deploy a 5 men
defense when defend and 5-men midfield when attack , remember that
Chelsea played a 2 men upfront , he has to put some muscle in the
middle , cos Ferreira was a more versatile player both in defense
and attack , and he has height , Cole was obviously a better option
in terms of attack , but not in the case of defense , and Cole
doesn't possessed any height advantage .
Mourinho was back-fire with this set-up .
One more analysis , Ferreira was appointed Man-Marker on Gerrard
.
Just my 3-cents worth of analysis .
