He states :
"We've had a strategy that we have agreed on. There was some disconnect on the implementation of that".
"That strategy is a strong one and it will continue. We need to build a strong system under the first team."
So for me Comoli actually fired for not signing enough young players with potential who could be developed into first team players. If you have a look only Danny Ward and Jordan Ibe who were signed in Jan 2012 meet this criteria.
All the rest of the players signed under Comoli tenure as DOF were signed to come straight into the first team.
