Jagielka and Distin 10 yards further up the pitch defending doesn't bare thinking about.
I know, that's why they drop back because they are incapable of playing the "Martinez way", it's why we are slow and pass it around the defence for no reason, we are getting pushed backwards rather than pushing forwards looking to attack the opposition.
If Martinez wants to play "his" way he needs to get a new CB in this window and another one in the summer to replace Jags and Distin. They are not good enough for Martinez's philosophy.
