I'm happy that the FD have sent a message to Dunn. His form in 2010 and 2014 was good. But that's it! Last year he was again poor and that's reflected in the B&F results. The games he's played this year have also been poor (undisciplined, poor coverage of the ground, lazy, etc).
For a senior player he does not do enough and never really has. They might as well try and blood replacements. It's a good message to the rest of the group.
