Train as you aim to play

Apparently from what I have read Clichy has been surprised, that in training City players tackle hard and “train as they aim to play". I guess we all saw the headlines last season when City players got a little carried away. Lee Dixon has continually defended the training skirmishes at City, stating that this is something that used to happen back in the day at Arsenal.
This got me thinking, do you think it would benefit your players and make you a less “easy to bully" if you trained with more intensity.
